4. The system of claim 1 , wherein each extracted Kashida is classified based on at least: a width of the extracted Kashida, a slope of an upper contour direction (UCD) of the extracted Kashida, and a slope of a lower contour direction (LCD) of the extracted Kashida.
4. The system of claim 1 , wherein each extracted Kashida is classified based on at least: a width of the extracted Kashida, a slope of an upper contour direction (UCD) of the extracted Kashida, and a slope of a lower contour direction (LCD) of the extracted Kashida. 5. The system of claim 4 , wherein the circuitry is further configured to: generate a width probability density function (PDF) for each of the width, UCD and LCD of the extracted Kashida, wherein the width PDF is generated based on one or more selected square bins having a width of 8-pixels, and discard extracted Kashida having a width of less than 6-pixels.
