To obtain both features, some pre-processing steps, such as object segmentation using Minimum Error Thresholding and border extraction, are firstly carried out. After that, the Grid Based method is used to(More)
In this paper, we present a noise model for generating synthetic character databases to train Optical Character Recognition (OCR) systems. Nowadays, the emergence of new font typefaces requires an imperative task to automatically and rapidly generate synthetic training character databases. In addition, since the accuracy of the OCR systems deeply depends on(More)
