摘要：Signing documents is something that most everyone is familiar . In our daily lives we sign everything from personal checks to birthday cards. So it is necessary to determine the authenticity and genuineness which require certification using signatures. Most signature verification schemes till date have required perfect alignment of the signature to the specified axes. However there are situations when the sample to be verified may not be aligned to the required axis. In that situation the current verification schemes could reject the signature even though it may be genuine. Though various techniques are available for verification of cheques before Clearing, there are possibilities of unavoidable errors. Inconsistent handwritten Character's pattern & alignment errors. In order to avoid this, a system that not only flags the cheques to be impounded, but also take it through cross-pattern verification to acclaim the authoritative cheques.The suggested technique aims to make the verification of signatures size and angle invariant. The invariance can be achieved by scaling and rotational manipulations on the target image. We propose a methodology that verifies a cheque by recognizing and analyzing the major details in a cheque, which includes the account holder's signature. It falls through image capturing, gray scale image conversion, Binarization, Edge detection, which is then localized & the signature is compared. Image captured is converted into a gray scale i\mage which resolute the authoritative regions in the cheque that includes the account bearer's signature. The contour classification ensures the segmentation of the characters on the cheque. It is then localized, and compared with the account holder's source of information and clarified and passed on. Any checks that are not successfully read and matched are highlighted as an exception and immediately forwarded to the client for further action
