[0044] The technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention.
[0045] The technical solution of the present invention to solve the above technical problems is:
[0046] A medical image segmentation method based on a lightweight fully convolutional neural network is characterized in that it includes the following steps:
[0047] Step 1: Perform grayscale, normalization, contrast-limited adaptive histogram equalization (CLAHE), and gamma adjustment on the data set to improve the segmentation quality of medical images;
[0048] Step 2: Because the amount of preprocessed data in step 1 is too small, in order to effectively avoid overfitting into a local optimal solution during deep network training, this method extracts patches randomly from the training set and extra...
