Image processing method, apparatus, electronic device and storage medium

An image processing apparatus, comprising:

• at least one processor;
• and
• a memory communicatively connected to the at least one processor;
• wherein,
• the memory stores instructions capable of being executed by the at least one processor, and the instructions are executed by the at least one processor, so that the at least one processor is configured to:
• acquire an image to be processed;
• acquire a grading array according to the image to be processed and a grading network model, wherein the grading network model is a model pre-trained according to mixed samples, the number of elements contained in the grading array is C−1, C is the number of lesion grades, C lesion grades comprise one lesion grade without lesion and C−1 lesion grades with lesion, and a kth element in the grading array is a probability of a lesion grade corresponding to the image to be processed being greater than or equal to a kth lesion grade, wherein 1≤k≤C−1, and k is an integer;
• output the grading array.
