How to using the color intensity of each fruit, segment the three different fruits.

This looks like a homework problem. If you have any questions ask your instructor or read the link below to get started:

How do I get help on homework questions on MATLAB Answers? - MATLAB Answers - MATLAB Central

Obviously, if it is homework, we can't give you the full solution because you're not allowed to turn in our code as your own. But search the forum for the tag "color segmentation" (click on the tag on the right hand side of this page) and you'll find lots of examples you can adapt.

One way could be to convert from RGB to HSV and do kmeans on the hue channel, since I think you'll find the most contrast in that channel. Since the apple has orange in it, you'll have to do a hole filling on each segmented color with imfill. Tell kmeans that k=4 since there are 4 colors there (red, orange, yellow, & white).

........ i already solve before view your answer, but thank , i just want to have the idea and any example of code source segment based on color for me to understand. because most example cannot help me understand and don't how to start, so i ask direct without specific. yes this is homework but i don't like turn in other code as my own.

How did you distinguish the apple and orange, especially the boundary between them, especially since both the apple and the orange have both red and orange in them?

use Define masks, don't use kmean. i can't give you the full solution, remember next time don't say "you the full solution because you're not allowed to turn in our code as your own. " respect people ask question wrong way. good luck

Where is the "Define masks" functionality? It's not an Image Processing Toolbox and I don't see it as one the App names in the Image Processing group (Apps tab of the tool ribbon). Where did you find it? Help me locate it.
