Please help to write a code for this: Lines detected by hough transform have to be deleted. Residual text in the signing area have to be identified and deleted.

You can do Otsu with bwthresh() and im2bw(). There are also functions for hough in the Image Processing Toolbox. I have not coded up that particular algorithm in that particular paper so I don't have code to give you. To find centroids, use regionprops() as in my Image Segmentation Tutorial at http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 That should be enough for you to at least get started with your coding. Good luck.

Search for OCR. I've written and uploaded things like this before. I don't have time to do anything on your project now and for a few days. You didn't even upload an image for anyone to do anything with even if they were going to.
