load image
pretraitment (i used median filter to remove noise )
segmentation (here i used PSO from https://www.mathworks.com/matlabcentral/fileexchange/29517-segmentation)
u can use FCM https://www.mathworks.com/matlabcentral/fileexchange/43987-original-fcm-for-image-segmentation

在 MATLAB Online 中打开

Lets say "seg_image" is the segmented image. Once segmentation, all regions have different pixels value, please check the pixel value of Gray Matter, White Matter, CSF. The respective resion must have same pixel value.

subplot(131),imshow(seg_image(seg_image==Gray_Matter_pixel value || seg_image==0);
subplot(131),imshow(seg_image(seg_image==White_Matter_pixel value || seg_image==0);
subplot(131),imshow(seg_image(seg_image==CSF_pixel value || seg_image==0);

Any issue let me know?
