A Novel Method for Slant Correction of Persian Handwritten Digits and Words

In this paper, a new slant estimation/correction method for Persian handwritten digits and words is presented. Based on the presented method, first using original image and itsinversion, a new combined image is constructed. This new image has the same slant as the original image. So its slant is estimatedand considered as the slant of original image. Finally, using a shear transformation, the slant of the original image is corrected.The performance of the presented method has been tested usingseveral popular Persian/Arabic databases. Obtained experimental results and comparison with the other methods in the literature confirm that the presented method is accurate, and promising.
