Hi all
I have apply this code to crop my images in any sizes
B = imread('bar5.jpg');
B = imresize(B,0.33);
B2 = im2bw(B1);
stat = regionprops(I,'area');
C(1:length(stat)) = stat(1:end).Area;
m = max(C);
J = bwareaopen(I,m);
imshow(J);
and I got this message
??? Undefined function or variable 'I'.
so any ideas
sorry I'm new in matlab
I want learning
Thanks

After the line
B2 = im2bw(B1);
add the line
I = B2;

You can do this:
stat = regionprops(B2,'area');
allAreas = [stat.Area];
maxAreas = max(allAreas);
You didn't do any cropping (perhaps you meant "size filtering" instead). You just took your image and threw away all the objects smaller than the largest object by using bwareaopen(). In other words, you threw EVERYTHING away.
