Hey there ! I have an image and it contains 5 bright regions ,after thresholding I want to get the pixel indices or x,y coordinates of those five regions in 5 different arrays. How this should be done ?

Answer 1

binarize the image, use regionprops,

get the PixelList properties and use bwconncomp to identfy separate objects in the selected pixels corresponding to the different objects.
