Isolated Persian/Arabic handwriting characters: Derivative projection profile features, implemented on GPUs

For many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. However, an issue that has rarely been studied is the speed of these methods. Considering the computer hardware limitations, it is necessary for these methods to run in high speed. One of the methods to increase the processing speed is to use the computer pa...

PROJECTION Algorithm for Motif Finding on GPUs

Motif finding is one of the NP-complete problems in Computational Biology. Existing nondeterministic algorithms for motif finding do not guarantee the global optimality of results and are sensitive to initial parameters. To address this problem, the PROJECTION algorithm provides a good initial estimate that can be further refined using local optimization algorithms such as EM, MEME or Gibbs. Fo...

Exploring the Ability of Parts on Recognizing Handwriting Characters

This paper shows an experimental trial on part-based online character recognition. The purpose of the trial is to evaluate the discrimination ability of parts of a handwriting character, that is, a temporal pattern showing a character. Each part is a temporal segment of the character and the character is decomposed into a set of parts. Those parts are then represented as a “bag-of-features”, wh...

Lexicon Reduction Based on Global Features for On-line Handwriting

Handwriting Recognition generally uses a dictionary : in the case of large vocabularies, our system helps checking the existence of the words provided by the recognizer, or when there is a model to go through per word, it will reduce the number of models to go through. In the case of smaller vocabularies it can be used as a recognizer. From the signal provided by a digitizing tablet we build a ...
