Pre-processing of handwritten signature images for following recognition

چکیده
In the process of handwritten signature recognition, preprocessing is an important step before calculation its informative features. Signatures any person always have some differences, in addition, they can be different colors, sizes and orientations. After digitization, their images may contain noise. The purpose image to obtain most invariant representation digital a person's signature, which will allow us identify him or define that forged. This paper describes sequence transformations necessary perform form single orientation size. It assumed there are no graphic elements not related background relatively uniform. under consideration sequentially binarization image, filtering, rotation, cropping circumscribed rectangle scaling fixed described procedures were applied number available databases, such as CEDAR, BHSig260-Bengali, BHSig260-Hindi. Experiments on recognition confirm presented approach leads increasing accuracy.

This paper presents the results of Persian handwritten word recognition based on Mixture of Experts technique. In the basic form of ME the problem space is automatically divided into several subspaces for the experts, and the outputs of experts are combined by a gating network. In our proposed model, we used Mixture of Experts Multi Layered Perceptrons with Momentum term, in the classification ...
متن کاملChaincode Contour Processing for Handwritten Word Recognition
ÐContour representations of binary images of handwritten words afford considerable reduction in storage requirements while providing lossless representation. On the other hand, the one-dimensional nature of contours presents interesting challenges for processing images for handwritten word recognition. Our experiments indicate that significant gains are to be realized in both speed and recognit...
