Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] The method for locating and classifying the lesion area of the medical image of the present invention automatically locates the lesion area first, then divides the image to retain the lesion area, and then trains the segmented image with a deep learning model, which can greatly improve the accuracy of classification. The flow chart of the invention is as follows figure 1 shown.
[0025] Specific steps are as follows:
[0026] 1) Extract WLD histogram features
[0027] For a given image, the WLD histogram features are extracted using differential excitation ξ and gradient direction θ.
[0028] A. Calculating differential incentives ξ
[0029] The sum of the grayscale difference between the center pixel and all its neighbor pixels is v 00 express:
[0030]
[0031] Among them, p represents the number of adjacent points, v i Represents the gray level o...
