I want to label a set of pictures like this one, which are only made up of three colors. I'm currently using Image labeler (more specificly the flood fill) to label its pixels. However it cost to much time. I want to assign labels to each pixels according to the color of the pixel. Can anyone help me?

Hi Muchen!
You can use 'categorical' function to convert array into lable form.
