Steps:
- Get the Centre Blobs
- Make it color as per your requirements, please note that resultant color image will be RGB image, not binary
Here, bwImage represents the binary image
bwImage=bwareafilt(~bwImage,1);
bChannel=255*uint8(bwImage);
gChannel=255*ones(size(bwImage),'uint8');
colorImage=cat(3,bChannel,gChannel,gChannel);
imshow(colorImage);
Hope it Helps!
