This work proposes to authenticate offline signatures using a Case-Based Reasoner (CBR). The case base serves as a repository of sets of genuine signatures for which a central point on the n-dimensional global feature space is preserved along with the Inter-Quartile Range (IQR). These signatures are paired off to perform Dynamic Time Warping (DTW) comparison on their respective contours. Metrics generated...
Script identification from handwritten document images is an open document analysis problem especially for multilingual environment like India. To design the Optical Character Recognition (OCR) system for multi-script document pages, it is essential to recognize different scripts prior to employing an OCR engine of a particular script.
