[ask] how to fix reshape error

hello everyone, btw i have a sample code like this :

[img_rgb, clrMap] = imread ('E:\FOTO\C360_2015-02-02-14-15-52-544.jpg');
[rows,columns,numclrchannels] = size(img_rgb);         
img_hsv = rgb2hsv(img_rgb);
h_img=img_hsv(:,:,1);
s_img=img_hsv(:,:,2);
v_img=img_hsv(:,:,3);
nSteps = 3;

[center,U,obj_fcn]=fcm(h_img,nSteps);
[~,cluster_idx] = max(U); 

subplot(1,2,1);
imshow (img_hsv);
subplot(1,2,2);
pixel_labels = reshape(cluster_idx,rows,columns);
imshow(pixel_labels,[]), title('image labeled by cluster index');

i want to label every cluster created on the HSV image processed by FCM function.

but the problem is i always have an error on displaying the output of pixel_label saying :

Error using reshape
To RESHAPE the number of elements must not change.

is there any other way to display HSV output image after the HSV image has been processed by FCM function properly? How to fix the error?

thx before.

Without testing it out, I suspect that you need to change

[~,cluster_idx] = max(U);

to

[~,cluster_idx] = max(U, [], 2);

so that you take max across rows.

it finally works anyway but i don't get desired results....what should i do?? should i change the way it outputs the FCM results?

[Walter Roberson]

Your original max() was correct. But you need

[center,U,obj_fcn]=fcm(h_img(:),nSteps);
