Embodiment Construction

[0053] In order to make the features and advantages of this patent more obvious and easy to understand, the following special examples are described in detail as follows:

[0054] Such as figure 1 As shown, the algorithm provided by this embodiment includes three parts: an image preprocessing part, an image segmentation part, and a treatment effect evaluation distribution part.

[0055] The algorithm flow is as follows: 1. The computer reads the captured lesion images. 2. Decompose the lesion image into grayscale images of three channels, such as Figure 2-Figure 5 shown. 3. Set the threshold according to the characteristics of the lesion and perform image binarization segmentation, such as Figure 6shown. 4. Perform image optimization processing such as morphological closing operation on the segmentation results, use the image opening and closing operations to eliminate the noise part of the binarized image, and extract the ROI (region of interest) lesion area and isolate...

Abstract

The invention provides a skin pigment lesion treatment effect image processing method based on feature segmentation, and the method is characterized in that skin pigment lesion color images in the same region before and after treatment are processed through the steps S1 to S5: S1, converting the color images into three-channel RGB gray images; S2, coarsely extracting a focus area; S3, carrying out a repairing and closing operation; s4, calculating to obtain an area with uneven illumination of the picture; s5, low-pass filtering processing is carried out, and an actual focus area distribution map is obtained; and S6, establishing a treatment effect image evaluation model. According to the method, the focus area is segmented, the ROI area is extracted, the background light intensity of the segmented area of the image is eliminated, and the problem of background light influence in the shooting process is solved. The practical work of clinical image analysis is guided to a great extent, and a facial pigment lesion recording, analyzing and evaluating technology with high practicability is provided.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a feature segmentation-based image processing method for the treatment effect of pigmented skin lesions. Background technique [0002] PWS is a congenital pigmented skin disease. The cause is abnormal growth of capillaries in the skin, which leads to bright red spots on the surface of the skin. With age, the lesion area will increase and last forever. subside. Due to the influence of human subjective factors on the evaluation indicators of the treatment effect of port wine stains, the current evaluation scheme of the treatment effect is still based on subjective judgment, lacking objective and accurate data analysis. [0003] Digital image processing is a method and technology for computers to remove noise, enhance, restore, segment, and extract features from images. Extract certain features or special information contained in the image, these extracted features or i...
