Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of a method for adjusting a medical electronic film image according to an embodiment of the present invention. Referring to fig. 1, a method for adjusting an electronic film image for medical use, includes:
step 101: and acquiring a film image to be adjusted.
After the medical equipment takes the image of the patient, the image is taken as the film image to be adjusted. The conditioning device in this application can obtain the film image to be conditioned from the medical device.
Step 102: and dispersing the film image to be adjusted into a preset image adjusting coordinate system.
After the film image to be adjusted is obtained, in order to adjust the color lookup table in the film image to be adjusted, the film image to be adjusted is dispersed into a preset adjustment map coordinate system of 600 pixels by 600 pixels. The preset image-adjusting coordinate system can be used for accurately acquiring the position information of the film image to be adjusted, and coordinates are distributed to each pixel point in the film image to be adjusted, so that the black-white color concentration of the film image to be adjusted can be conveniently and accurately controlled. It should be noted that the size of the preset map coordinate system is not limited to the size set in the above embodiments, and may be determined according to actual situations.
Step 103: and receiving operation data of a user, and determining a chart adjusting key point selected by the user on a preset reference curve in the preset chart adjusting coordinate system according to the operation data.
When the film image to be adjusted is adjusted, the adjusting device can display an image color lookup table adjusting interface to a user. When the film image to be adjusted is dispersed to the preset chart coordinate system, the current interface can display the preset chart coordinate system which is opposite to the film image to be adjusted and the film image to be adjusted to the user. At the moment, a preset reference curve is arranged in the preset chart coordinate system, and then a user can independently select chart adjusting key points on the preset reference curve according to the actual image condition of the film image to be adjusted. When the user selects the key point of the chart adjustment, the user can select the key point according to the display condition on the film image to be adjusted displayed on the current interface. For example, the image at the position a in the preset reference curve corresponding to the film image to be adjusted is blurred, the black and white level is not clear, and at this time, the user sets the position a as a key point of image adjustment on the preset reference curve.
The number of key points of the chart adjustment is not fixed, can be a plurality of key points, and can also be one key point, and the specific number is selected according to the requirements of users and the definition of the film image to be adjusted. The definition of the image can also be improved by changing the number of key points of the image.
Step 104: and moving the position of the key point of the chart adjustment, and carrying out black-and-white concentration adjustment on the film image to be adjusted by combining a Bezier curve algorithm until a target electronic film image meeting the requirements of a user is obtained.
After the key point of the chart is selected, the user controls and moves the position of the key point of the chart on the current interactive interface, in the process of moving the position of the key point of the chart, the image display definition at the position of the key point of the chart is changed, the black and white level is changed, and the user can set the key point of the chart at the position with clear black and white level. Meanwhile, in the process of moving the key point position of the chart, the image near the key point position of the chart is properly adjusted by combining a Bezier curve algorithm. The Bezier curve algorithm can adjust the black-white concentration of the image near the key point of the tone map while adjusting the black-white concentration of the key point of the tone map, and the color difference between the key point image and the surrounding image is abrupt.
In the above embodiment, the film image to be adjusted and the preset chart coordinate system are combined in an antipodal manner, the preset reference curve is set in the preset chart coordinate system, the user selects the chart adjusting key point on the preset reference curve in contrast to the color display condition of the film image to be adjusted, and then the user adjusts the black-and-white density of the image at the key point position by moving the position of the chart adjusting key point. Meanwhile, a Bezier curve algorithm is combined in the adjusting process, so that the effect of smoothing the preset reference curve passing through a plurality of key points is achieved, and the optimal effects of clear gradation and no color fault of film image imaging are achieved.
To describe the method for adjusting an electronic film image in more detail, another embodiment is provided on the basis of the above embodiment, and the following is provided.
Fig. 2 is a flowchart of a method for adjusting a medical electronic film image according to another embodiment of the present invention.
Referring to fig. 2, a method for adjusting an electronic film image for medical use includes:
step 201: and acquiring a film image to be adjusted.
Step 202: and judging whether the film image to be regulated is an 8-bit map.
In the process of electronic film image adjustment in this application, the image used needs to be an 8-bit map image. Thus, after receiving the film image to be adjusted, it is necessary to determine whether the film image to be adjusted is an 8-bit map.
Step 203: and if the film image to be adjusted is not the 8-bit map, converting the film image to be adjusted into the film image to be adjusted in the form of the 8-bit map.
When the acquired film image to be adjusted is not an 8-bit map image, the film image to be adjusted needs to be converted into an 8-bit map image, and the following operations can be performed on the basis.
It should be noted that, in the present application, the condition that the film image to be adjusted is set to be the 8-bit map image is not fixed, and the pixels of the film image to be adjusted may not be set, or other criteria may be set, which may be determined according to the actual application scenario.
Step 204: and converting the film image to be adjusted into a 24-gray-scale image.
In the present application, a basic 24-level gray scale map is used for adjusting the image color lookup table. I.e., the film image to be conditioned is divided into images having 24 square areas. The 24 gray-scale images can be used for accurately dividing the area of the film image to be regulated, so that the preset chart coordinate system can be accurately corresponded.
Step 205: and correspondingly dispersing the 24 gray-scale images into the preset tone image coordinate system.
Step 206: and receiving operation data of a user, and determining a chart adjusting key point selected by the user on a preset reference curve in the preset chart adjusting coordinate system according to the operation data.
Before a user selects a key point of a chart, a preset reference curve needs to be generated in advance. The mode that generates in this application and predetermines the benchmark curve has two kinds, one kind is that this application transfers the picture software system can directly demonstrate to the user and predetermine the curve storehouse, should predetermine the curve storehouse and have had multiple curve, and the user can be according to actual need early should predetermine the curve storehouse in select required curve as predetermineeing the benchmark curve can. The other is that the user can select a certain position as a preset reference curve in a self-defining way on the interactive interface. The specific generation mode of the preset reference curve is not fixed and is determined according to the actual requirements of users and the actual conditions of the film images to be adjusted.
One end of the preset reference curve is the lower left corner in the preset coordinate system, and the other end is the upper right corner in the preset coordinate system. I.e. the diagonal line in the predetermined coordinate system, which is the diagonal line connecting the lower left corner and the upper right corner. And setting the color of the lower left corner of the preset reference curve connected with the preset coordinate system to be black, and gradually reducing the color concentration along the curve direction until the color of the curve connected with the upper right corner of the preset coordinate system is white.
Step 207: and carrying out up-and-down movement operation on the key points of the chart adjustment on the preset reference curve, and carrying out black-and-white concentration adjustment on the film image to be adjusted at the corresponding positions of the key points of the chart adjustment.
After the key point of the chart is selected, the key point of the chart is moved up and down, and then the black and white density of the image at the position of the key point can be adjusted. For example, moving down the black color at the position is deepened, and moving up the white color at the position is deepened. By adjusting the black-white concentration, the black-white level in the image can be adjusted, and the image definition can be further changed.
Step 208: and carrying out black-and-white concentration adjustment on the film image to be adjusted within the set range of the key points of the image adjustment by using a Bezier curve algorithm, and displaying an operation interface for adjusting the black-and-white concentration of the film image to be adjusted in real time.
The method can adjust the black and white concentration of the electronic film image by moving the position of the key point of image adjustment, so that the image imaging achieves the best effects of clear gradation and no color fault. And in the process of moving the chart key points, the change condition of the black and white concentration in the moving process is displayed in real time, so that the function of timely feeding back the adjusting effect is achieved. Thereby reducing the adjustment time and reducing the waste of film consumables.
