Sean, I can see the enthusiasm in your eyes in your profile picture.

HaHa Sean is a funny guy. I need a useful code to separate this three area. I tried lots of methods including the "Color-based Segmentation of Fabric Using the L*a*b Color Space" which in the MATLAB own method dictionary.

Thank you both of you and i will post the image to your email.

在 MATLAB Online 中打开

I would filter by the red color plane.

See below:

myImage = imread('too-much-red-meat101.jpg');
rPlane = myImage(:,:,1) - 0.5*(myImage(:,:,2)) - 0.5*(myImage(:,:,3));
red = rPlane > 100 ;
white = rPlane < 5;
pink = rPlane > 5  & rPlane < 100;
figure
imshow(red)
figure
imshow(white)
figure
imshow(pink)

I tried this on a picture from google images and it seemed to work well. You probably need to pick different criteria for red, white, pink, and black. My photo only had red, white and pink.

Ironically, this answer was written by a strict vegetarian!

That last comment was immediately what I thought when I saw that you'd answered. Excellent. Also: I think this question wins the "Best Question Title Ever" award.
