Hi dear;
I have a binary image that contains an object (some times a lot of objects), I want to reshape the object as showing in the image 1 to the one as showing in the image 2. My goal is to have an object tha has a straight boundaries.
Any help and suggestion will be appreciated.

Maybe you would like to skeletonize, remove spurs, and then dilate out again??

Use
[labeledImage, numBlobs] = bwlabel(binaryImage);
measurements = regionprops(labeledImage, 'BoundingBox');
then for each blob in a for loop over all blobs, get the bounding box and get the bounding rows and columns,
for k = 1 : numBlobs
xLeft = ceil(measurements(k).BoundingBox(1));
% etc.
binaryImage(yTop:yBottom, xLeft:xRight) = true;
end
Let me know if you can't figure out the rest.

Aha, we knew it! You didn't actually want what you asked for (and so all my prior effort went to waste, perhaps). Now, with this image it looks like you actually want some kind of "envelope" of the blob. So it seems like you want activecontour(). This time I'll simply attach my canned demo and you can adapt it yourself.
