Embodiment 1
[0043] A robust interactive medical image segmentation method, comprising the following steps:
[0044](1) The original OCT image without processing, such as figure 1 As shown, the original OCT image is first regularized, and the purpose of the regularization is to normalize the pixel values of the original image to the range of [0,1]; then the fractional differential enhancement is performed on the image, the purpose is to reduce Influenced by speckle noise, the specific process of fractional differential enhancement is as follows:
[0045] First, the n×n fractional differential enhancement mask is obtained using a discrete method, such as figure 2 As shown, any element Γ(-v+1) represents the gamma function of (-v+1), Γ(-v+i+1) represents the gamma function of (-v+i+1), i! Represents the factorial of i, where n=5, v=0.2;
[0046] Then, the image is convolved with an n×n fractional differential enhancement mask to complete the fractional differential enhancement of the...
