Detailed ways

In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation of the 5G technology-based gastrointestinal medical image communication transmission method proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. , structure, feature and effect thereof are described in detail as follows. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures or characteristics of one or more embodiments may be combined in any suitable manner.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention.

The specific scheme of the 5G technology-based gastrointestinal medical image communication transmission method provided by the present invention will be described in detail below with reference to the accompanying drawings.

Please refer to Fig. 1, which shows a method flow chart of the data transmission module of the 5G technology-based gastrointestinal medical image communication transmission method provided by an embodiment of the present invention, the method includes:

S001. Obtain the data sequence and all kinds of gray values.

Specifically, the gastrointestinal medical image is converted into a data sequence according to the zigzag scanning mode, and the data in the data sequence are gray values of pixels in the gastrointestinal medical image.

S002, calculate the gray value coding lengths of all possible length groups, calculate the run length coding lengths of all possible length groups, and obtain the first length corresponding to the target length group according to the gray value coding lengths and run length coding lengths of all possible length groups The second length and the longest run length.

It should be noted that when performing lossless coding on a sequence, if the compression efficiency of the coding result of the image coding is to be maximized, the coding length is required to be equal to the information entropy of the sequence, but the coding length is an integer, and the information entropy of the sequence is not necessarily an integer. This results in that the compression efficiency of the coding result of image coding cannot be maximized. The sequence is encoded by setting two different encoding lengths, so that the average encoding length may not be an integer, thereby maximizing the compression efficiency of the encoding result of image encoding.

It should be further noted that although setting two different encoding lengths can maximize the compression efficiency of the encoding result of image encoding, the mixing of the two different encoding lengths in the encoding result of image encoding will cause the encoding result of image encoding to be inconsistent. It has decodability. Therefore, this embodiment considers that the two encoding lengths appear alternately in the encoding result of image encoding, but the distribution of data in the actual sequence is various, and it is impossible to completely obey the alternating appearance of the two encoding lengths. Therefore, in this embodiment, by expressing the continuous data with the same coded length without alternate occurrence, that is, with the run length, the two coded lengths in the coded result of image coding can be realized alternately, so that the coding of image coded with two different coded lengths The result is decodable.

(1) Calculate the lengths of gray value codes of all possible length groups.

It should be noted that the encoding corresponding to the two encoding lengths must be able to encode all kinds of gray values in the sequence, and at the same time, the encoding result of the sequence should be as short as possible, so as to maximize the compression efficiency of the encoding result of image encoding.

Specifically, will satisfy and/> Any two positive integers s1 and s2 are recorded as a possible length group (s1, s2), and N represents the number of types of all kinds of gray values in the data sequence; the frequency of each gray value in the statistical data sequence, all The gray values are arranged in the order of frequency from large to small; according to the principle of assigning shorter codes to gray values with larger frequencies and longer codes to gray values with smaller frequencies, the calculation The gray value encoding length of each possible length group, the specific calculation formula is:

In the formula, Indicates the gray value encoding length of the possible length group, s1 and s2 respectively represent two positive integers that make up the possible length group, /> Indicates the frequency of the jth gray value after sorting, and N represents the number of types of all gray values in the data sequence.

(2) Calculate the run-length code lengths of all possible length groups.

It should be noted that, in this embodiment, the remaining codes are used to represent the run lengths. Therefore, the number of run lengths that can be represented by codes is limited, and the actual number of run lengths may be greater than the number of remaining codes. In order to ensure that all run lengths The length of the run is coded. For the longer run length, the shorter run length can be used to represent the longer run length; for example: when the possible length group is s1=2 and s2=3 and N=7, the remaining This type of encoding can be used to encode the shorter run lengths 1 to 5, and for the longer run length 9, it can be represented by the shorter run lengths 1 to 5. In order to make the encoding result the shortest, the length The longer run length 9 is split into as few as possible shorter run lengths, and then expressed by the longest run length 5 among the shorter run lengths with the most length as possible, based on this, the possible length group is obtained The length of the run-length code.

Further, according to the run length in the run length encoding result of the type sequence, the run length encoding length of the possible length group is calculated, and the specific calculation formula is:

In the formula, Indicates the run length encoding length of the possible length group, M indicates the number of run lengths in the run length encoding result of the type sequence of the possible length group, s1 and s2 respectively indicate two positive integers that make up the possible length group, N indicates all of the data sequences The number of types of gray values, / indicates the division quotient, /> Indicates rounding up, /> Indicates the i-th runlength in the result of run-length encoding of a sequence of types representing a set of possible lengths.

(3) Obtain the first length, the second length and the longest run length corresponding to the target length group according to the gray value coded lengths and run-length coded lengths of all possible length groups.

Specifically, the sum of the gray value coding length and the run length coding length of the possible length group is recorded as the total coding length of the possible length group; the possible length group with the smallest total coding length is taken as the target length group, and the two positive integers are recorded as the first length S1 and the second length S2 respectively, and It is recorded as the longest run length Y2, and 1 is recorded as the shortest run length Y1.

S003. Assign codes to all gray values and run lengths according to the first length and second length corresponding to the target length group and the longest run length, and obtain a code table.

It should be noted that, in order to maximize the compression efficiency of the encoding result of image encoding, according to the encoding with the shorter length assigned to the gray value with the larger frequency, and the encoding with the longer length assigned to the gray value with the smaller frequency The principle of , and assigning the remaining codes to the run lengths, obtains the code table.

Specifically, give the sorted former A binary number whose length is equal to the first length is assigned to a gray value, that is, the binary number whose length is equal to the first length is used as the sorted front> encoding of gray values, s1 represents a positive integer that forms a group of possible lengths; assign a binary number whose length is equal to the second length to all remaining gray values, that is, a binary number whose length is equal to the second length is used as all remaining gray values encoding of the value; the remaining binary numbers of length equal to the second length are assigned to all runlengths between the shortest runlength and the longest runlength; encodings of all gray values and runlengths form an encoding table.
