This paper presented a two step method for offline handwritten Farsi word recognition. In first step, in order to improve the recognition accuracy and speed, an algorithm proposed for initial eliminating lexicon entries unlikely to match the input image. For lexicon reduction, the words of lexicon are clustered using ISOCLUS and Hierarchal clustering algorithm. Clustering is based on the featur...
The buoyant density of human platelets is decreased after they have been aggregated and induced to secrete their granule content by thrombin. This change in density was detected by discontinuous density gradient centrifugation using arabinogalactan (Stractan) solutions. The density decrease was dependent on the thrombin concentration and paralleled the extent of serotonin and beta-thromboglobul...
in this paper we address the issue of recognizing farsi handwritten words. two types of gradient features are extracted from a sliding vertical stripe which sweeps across a word image. these are directional and intensity gradient features. the feature vector extracted from each stripe is then coded using the self organizing map (som). in this method each word is modeled using the discrete hidde...
