1. A method for Arabic handwriting recognition, the method comprising: acquiring, an input image representative of a handwritten Arabic text from a user; partitioning, using processing circuitry of a server, the input image into a plurality of regions; determining, using the processing circuitry, a bag of features representation for each region of the plurality of regions; modeling, using the processing circuitry, each region independently by multi stream discrete Hidden Markov Model (HMM); and identifying, using processing circuitry, a recognized text based on the HMM models.
