Neural Network Code for Image Classification/Segmentation

I have written a code in Matlab for neural network classification/segementation the image after train the image. But, it is not working as expected. I get the error in this line "yhat = net(double([r;g;b]));". Is there any mistake in the code? Can you take a look at the code and help me out !!
a = imread('C:\Users\user\Desktop\MATLAB PROCESSING\Matlab Processing\Band432\open land\klang.tif');
b = rgb2gray(a);
figure, imshow(a);
figure, imshow(b);
thr = 0.5;
for i = 1:1:size(a,1)
for j = 1:1:size(a,2)
pix = a(i,j,:);
r = pix(1,1,1);
g = pix(1,1,2);
b = pix(1,1,3);
yhat = net(double([r;g;b]));
if yhat >= thr
result = 1;
b(i,j) = 255;
else
result = 0;
b(i,j) = 0;
end
end
end
figure3, imshow(b)
or any suggestion code for classify the image in 5-class
I really hope can get any feedback because I really not familiar with neural network toolbox

I don't know. However, searching on
NEURAL IMAGE SEMENTATION
resulted in 32 hits in ANSWERS and 33 hits in the NEWSGROUP.
Hope this helps.
