Thanks for everyone who tried to help me. Finally I found the simple way to do it. this is a really awesome method. bwconvhull(Iout)
This is the code segment;
if true
LB = 100;
UB = 100000;
IL = bwlabel(Ifill);
R = regionprops(Ifill,'Area');
ind = find([R.Area] >= LB & [R.Area] <= UB);
Iout = ismember(IL,ind);
%Ibw1=imcomplement(Iout);
CH = bwconvhull(Iout);
%Ibw3=imcomplement(CH);
[Ilabel num] = bwlabel(CH);
Iprops = regionprops(Ilabel);
Ibox = [Iprops.BoundingBox];
Icrop = imcrop(I,Ibox);
resized=imresize(Icrop,[100 100]);
end

This can also be solved using the algorithm I laid out in your previous question http://www.mathworks.com/matlabcentral/answers/132000#answer_139060

Thank you very much for helping me.I didn't know it.I have done all other things and I am stuck in cropping. It seems very simple. But I couldn't do yet.
I changed it as you said for 3 channels. Then there are no errors. But cropping is still not happened.Output is below,

You need to invert your binary image since it's darker than the background. You can either flip the > sign when doing thresholding (which is the easiest) or you can do it in a separate steps (more time consuming) binaryImage = ~binaryImage.

What is this for? Why don't you start your own new question?
