rgb = imread('peppers.png');            %'D:\OLD L\HSV_segment\42049.jpg'
 cform = makecform('srgb2lab');
 lab = applycform(rgb,cform);
ab = lab(:,:,2:3);
nrows = size(ab,1);
ncols = size(ab,2);
ab = reshape(ab,nrows*ncols,2);
nColors = 3;
[cluster_idx, cluster_center] = kmeans(ab,nColors,'distance','sqEuclidean', 'Replicates',3);
pixel_labels = reshape(cluster_idx,nrows,ncols);
figure,imshow(pixel_labels,[]), title('image labeled by cluster index');
