Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
A flow logic diagram of a data processing method provided by the present disclosure is illustrated with reference to fig. 1. In the method, after acquiring a target image, an encoder searches a target image sequence corresponding to the target image according to a pre-stored image sequence, encodes the target image according to the target image sequence, then sends the encoded image to a decoder, and the decoder searches the pre-stored image sequence according to encoded data, searches the target image sequence corresponding to the target sequence identification information, and decodes the target image according to the target image sequence. Specifically, the left "storage logic schematic" and the right "storage logic schematic" are the correspondence between the reference frame of each image sequence and the sequence number of each image sequence, the left "storage logic schematic" is stored in the memory 1, and the right "storage logic schematic" is stored in the memory 2. In a scenario where the decoder and the encoder are closer, a memory may be used, and may be determined according to practical situations.
Example 1
An embodiment of the present disclosure provides a data processing method, as shown in fig. 1, where the method is applied to an encoding device, and the data encoding method includes the following steps:
101. And acquiring a target image to be encoded.
The target image in the method provided by the disclosure may include a terminal device remote control server, and the server responds to the interface image of the remote operation; and the method can also comprise that the terminal equipment accesses a server, and the desktop image sent by the server is also included.
The method provided by the disclosure can be that the server acquires the interface image responding to the operation instruction of the terminal equipment, and sends the target image to the terminal equipment so as to realize the technical effect of remotely controlling the server through the target image, and specifically, the target image can be encoded through an encoder in the server.
102. And according to a preset algorithm, when a target image sequence containing the target image is found in at least one preset image sequence, acquiring a preset reference frame and target sequence identification information corresponding to the target image sequence.
The predetermined image sequence may include a historical operating interface image of the server.
The method provided by the disclosure further comprises the step of creating a preset image sequence, wherein the preset image sequence can be generated according to images with the use rate higher than a threshold value in the history record, and can also be generated according to the operation interface image of the target software in the server. For example, when the server transmits the word operation interface image to the terminal device, the probability of the change of the toolbar image is smaller than the threshold value, so that the toolbar image is unchanged in daily use, and therefore, when the toolbar image is transmitted in a coding mode, the preset image sequence can be used as a coding reference image, so that the coding data amount is reduced.
Further, in the method provided by the present disclosure, sequence identification information may be generated for a preset image sequence, and the preset image sequence may be identified by the sequence identification information, so that a plurality of preset image sequences may be distinguished by the identification information, and the sequence identification information may be a sequence number.
After the preset image sequence is generated in the method provided by the disclosure, an image characteristic value corresponding to the preset image sequence and a preset reference frame of the preset image sequence are also obtained, and a mapping relation between each preset reference frame and each preset image sequence is established.
In a specific implementation, the method provided by the present disclosure may establish a correspondence between a preset image sequence and an image feature value by means of establishing a table, where each image sequence is labeled by a serial number, as shown in fig. 3 a: the image characteristic value corresponding to the image sequence number 1 is the characteristic value A, and the image sequence corresponding to the image sequence number 1 is the image sequence A.
Further, the method provided by the present disclosure may further establish a correspondence between the reference frame of each image sequence and the sequence number of each image sequence by establishing a table, as shown in fig. 5b, by looking up a table, it can be known that: the reference frame corresponding to the image sequence number 1 is an A reference frame, and the image sequence corresponding to the image sequence number 1 is an image sequence A.
The method provided by the disclosure can compare the target image frame with a preset image sequence through the image characteristic value, so as to judge whether the target image belongs to the preset image sequence, and the specific judging method comprises the following steps:
in the step, firstly extracting the image characteristic value of the target frame image, wherein the obtained target image characteristic value of the target image can be extracted from the target image by utilizing a perceptual Hash algorithm, such as an algorithm a-Hash, a p-Hash, a d-Hash and the like;
searching in the corresponding relation between the preset image sequence and the image characteristic value according to the extracted target image characteristic value, wherein the specific searching can be performed through the table in the figure 3 a;
If the target frame image can be found, the image sequence to which the target frame image belongs is a preset target image sequence, and a preset reference frame corresponding to the preset target image sequence can be used for encoding;
If the image sequence is not found, the image sequence to which the target frame image belongs is not a preset image sequence, and the reference frame corresponding to the preset image sequence cannot be used for encoding.
The above-mentioned finding the target image frame in the preset image sequence may be determined according to the difference value between the two: when the difference value between the image characteristic value extracted from the target frame image and the image characteristic value extracted from the preset image sequence is smaller than the preset characteristic value threshold value, the target frame image can be considered to belong to the image sequence corresponding to the preset image characteristic value.
It will be appreciated that images having image feature values belonging to the same image sequence are all relatively similar. The same reference frame can be used for inter-frame coding, the image quality is higher, and the code stream is smaller. Even in the scene of page switching, the image sequence of the image can be found according to the image characteristic value of the image, and then the reference frame corresponding to the image sequence is found.
For example, an a-Hash algorithm is used to extract an image feature value, and the preset feature value threshold may be a hamming distance (the hamming distance between 2 vectors is defined as the percentage of components different from 2 vectors), and specifically may be set to be (0.25); the image characteristic value extracted from the target frame image A is (1010101010), the image characteristic value corresponding to the preset image sequence A is (1010101011), the Hamming distance between the two is (0.1) and is smaller than the preset characteristic value threshold, and the target frame image A can be considered to be attributed to the image sequence A.
In a specific implementation process, if the preset image sequence includes multiple images, the images can be compared one by one to confirm which image includes the target frame image
The method for searching the reference frame corresponding to the target image sequence provided by the present disclosure may include:
According to the sequence identification information of the target image sequence to which the target image belongs, a reference frame corresponding to the sequence identification information is searched in a database, and the corresponding relation between the reference frame of at least one image sequence and the sequence number identification information of at least one image sequence is prestored in a memory of a specific server, so that the reference frame corresponding to the target image can be searched through the sequence identification information, and the specific search can be searched through a table in fig. 3 b.
103. And carrying out inter-frame coding on the target frame image according to the preset reference frame and the target sequence identification information to generate coded data.
The method provided by the disclosure performs inter-frame coding on the target image to generate coded data, and includes:
acquiring sequence identification information corresponding to the target preset image, wherein the sequence identification information can be the sequence number of the image sequence number;
And generating the coded data after marking the preset reference frame by the sequence identification information.
By the sequence identification information, the decoding device can find the reference frame used in the encoding of the target image, so that the decoding efficiency is improved, and of course, the encoding device and the decoding device synchronize the sequence identification information and the corresponding relation between the sequence identification information and the reference frame in advance.
When the target image is not found in the preset image sequence, the method provided by the disclosure generates a new image sequence according to the target image and performs coding processing. The encoder carries out intra-frame encoding on the target data to generate encoded data, wherein the encoded data carries sequence identification information of the new image sequence.
It will be appreciated that the encoder will perform intra-coding only in the case where the image to be coded belongs to a new image sequence, and the reference frame will be included in the coded data.
After the new image sequence is created, the method provided by the disclosure can send the new image sequence, the identification information thereof and the reference frame image to the encoding equipment, thereby ensuring that the same reference frame can be used for encoding and decoding and achieving the effect of improving the encoding and decoding processing efficiency.
In a specific practical process, an encoder in a server creates and stores a new image sequence, attributes the target image to the new image sequence, and sends the target image and identification information corresponding to the target image to a memory; the memory stores the target image as a reference frame for a new sequence of target images.
After receiving the sequence numbers of the target image and the target image sequence, the memory stores the target image as a reference frame of a new target image sequence, and establishes a corresponding relation between the reference frame of the new image sequence and the sequence number of the new image sequence.
The data processing method provided by the embodiment of the disclosure is applied to encoding equipment, when the encoding equipment acquires a target image, the encoding equipment firstly searches a target image sequence containing the target image in at least one preset image sequence, and when the target image sequence is found, acquires a preset reference frame corresponding to the target image sequence, and encodes the target image according to the preset reference frame.
In the method provided by the disclosure, each preset image sequence corresponds to a reference frame, and when the same image sequence is encoded, the reference frame corresponding to the image sequence is used for encoding; meanwhile, the decoding device stores the reference frames corresponding to the image sequences, the coded data of the same image sequence is decoded by using the reference frames corresponding to the image sequences. Therefore, in the scene of image switching, different reference frames are respectively used for images belonging to different image sequences so as to ensure the picture quality, and in addition, the number of the reference frames in the coded data sent to the decoding end by the coding end is less, so that the coded data quantity is smaller.
Example two
Based on the data encoding method provided in the embodiment corresponding to fig. 2, another embodiment of the present disclosure provides a data decoding method, which may be applied to the target image sent by the terminal device decoding processing server. Referring to fig. 4, the data processing method provided in this embodiment includes the following steps:

The coded data provided by the present disclosure includes a target image and target sequence identification information, where the target sequence identification information is used to indicate a preset image sequence corresponding to the target image.
302. And according to the target sequence identification information, when a target image sequence corresponding to the target sequence identification information is found in a preset image sequence, acquiring a preset reference frame corresponding to the target image sequence.
In the decoding method provided by the present disclosure, a preset image sequence list is stored, where the preset image sequence list includes image sequences and a sequence number corresponding to each image sequence, as shown in fig. 5a, it can be known by looking up a table: the image sequence corresponding to the image sequence number 1 is the image sequence A.
In the decoding method provided by the present disclosure, the corresponding relationship between the reference frame of each image sequence and the serial number of the corresponding image sequence of each image sequence is also stored, as shown in fig. 5b, as follows from the table lookup: the reference frame corresponding to the image sequence number 1 is the reference frame A.
In summary, in the decoding method provided by the present disclosure, a first correspondence between identification information and a preset image sequence is consistent with a second correspondence between identification information and a reference frame image corresponding to the preset image sequence. For example, the preset image sequence a corresponding to the sequence number 1 may be found in fig. 5a and 5b by the sequence number 1, or the reference frame a corresponding to the sequence number 1 may be found by the sequence number 1, that is, the reference frame a may be known to be the reference frame corresponding to the preset image sequence a.

if not, the preset image sequence is not included, the target image sequence corresponding to the data to be decoded is not included, the encoded data is generated by intra-frame encoding, and the reference frame required for decoding the encoded data is not stored in the memory 2.
In the method provided by the present disclosure, when a target image sequence corresponding to the target sequence identification information is not found in a preset image sequence, the target image sequence is created according to encoded data, which specifically includes:
decoding the encoded data to obtain a complete target image;
creating a new image sequence according to the target image and the target sequence identification information, and establishing a mapping relation between the target sequence identification information and the new image sequence;
and storing the target image sequence, the target sequence identification information and the mapping relation into a second memory.
Further, a new target image sequence can be processed, the target frame image is used as a reference frame corresponding to the target image sequence, and a mapping relation between the reference frame and target sequence identification information is established
Through the above-mentioned processing, in the decoding method provided by the present disclosure, when the encoded data generated by inter-frame encoding of the target image sequence is encountered next time, the new target image sequence is determined to be included in the preset image sequence list according to the identification information, such as the sequence number, carried in the encoded data, and then the required reference frame is acquired from the memory 2 according to the identification information.
303. And decoding the encoded data according to the preset reference frame to obtain a target frame image.
The method provided by the disclosure obtains a complete target image by decoding encoded data using the preset reference frame.
Furthermore, in order to improve the decoding efficiency, the present disclosure may further replace the reference frame corresponding to the image sequence to be decoded in the corresponding relationship with the target image, and through the replacing process, the reference frame corresponding to each image sequence stored in the memory may be continuously updated, so that the image during encoding and decoding is as close as possible to the reference frame, which not only can reduce the encoded data, but also can improve the image quality of the decoding process.
In the specific practical process of the method provided by the disclosure, the serial numbers of the decoded complete image and the decoded image sequence can be sent to a memory through a decoder; the memory replaces the reference frame corresponding to the sequence number of the parsed image sequence with the complete image, namely, the decoded complete image is used for updating the reference frame of the image sequence to which the complete image belongs.
