Farsi Font Face Recognition in Letter Level

Most of the presented papers about font recognition, are in block or line level. In this paper a new approach is presented which is able to recognize font of a Farsi document image in letter level. In this approach using the Euclidean distance between spatial descriptors and gradient value in each boundary point of some special Farsi letters in a document image its font is recognized. To implement and evaluate this approach we constructed a dataset consisting of some templates in 25 widely used Farsi fonts and another dataset including 500 Farsi document images. Obtained recognition rate was 98.7%.
