This paper also explains the procedure required for alignment and binarization of signatures. The entire process is covered in four stages: Image acquisition, Pre-processing, Feature extraction and Verification. Out of the four, this paper lays stress on first two stages. The work has been tagged appropriate after undergoing various stages of testing.
