segmentation medical image irm

I am doing Brain tissues MRI segmentation using PSO the output is 4 labels image (Gray Matter, White Matter, CSF) after doing segmetation i get this result . now how separate between this colors (classes) in subplots from this to this

Is it possible to give me a hint about how you do the segmentation, I need to do the segmentation for something else but also related to medical images

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

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?
