[0030] The present invention will be further described below with reference to the accompanying drawings.
[0031] Refer Figure 1 ~ 5 A intestinal lesion auxiliary diagnostic method based on non-standardized depth residual and attention mechanism, including the following steps:
[0032] Step 1: Enter the image data set x = {x 1 , X 2 , ..., x n }, Where the X matrix represents the data set, n represents the total sample number, X i ∈R 224×224×3 Indicates feature vector composed of three channel pixel values of input images, (X i Y i ) Represents sample I, Y i Indicates the sample category tag, its value is 0, which represents 1 means polyps, its value is 2 indicating ulcers, and after training a classification model, the characteristic vector X i For input, the result tag of the predicted output is 0, 1 or 2, so that it can judge whether it is normal, polyp or ulcer;
[0033] Step 2: Due to the size of the inner lesions in the intestinal data concentration, the shape change diff...
