Abstract: Transforming a paper document to its electronic version in a form suitable for efficient storage, retrieval, and interpretation continues to be a challenging problem. Signature is an individualistic identification of a person. It is an authentic identification because a signature cannot be copied by others. Signatures are a special case of handwriting subject to intra personal variation and inter personal differences. To counter check fraud and forgery of handwritten signatures, Signature extraction from printed text background and signature based document retrieval from a large dataset is necessary. A lot many techniques have been implemented successfully for both signature extraction and signature based document retrieval. This paper present techniques and methods evolved for signature extraction and signature based document retrieval.
