Hi am doing a project on offline signature recognition and verification.In which i have to make 100 segments of a skeletonized image and then i have to calculate area of each segment.Can anybody suggest me a code to do so.

first of all decide what kind of segmentation you require?? and should it be general like it segments every other image the same way.

Things to Google:

Image Segmentation Matlab
Skeleton Matlab

You have the general procedure already written in your main post, so why not try building the program it step by step instead of asking others to do it for you? There are tons of resources on the internet that could easily advance you enough to the point where you could ask an actual, Matlab related question.

Here is an academic based resource for offline signature recognition: http://www.visionbib.com/bibliography/char1022.html#KK8526

See my BlobsDemo. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 I segment out coins from the image and make a variety of measurements on them, including the area.

I'm not sure you've explored existing algorithms here: http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems because saying that you need any/all signatures to be exactly 100 segments seems totally bizarre and arbitrary. I would think that peoples signatures could be a variety of number of segments, depending on how many times they lifted the pen, or how many times the pen skipped ink. But I'm not an expert in signature verification so maybe you are using an algorithm already published and described in section " 23.4.6.4.1 Off Line Signature Analysis"
