the gray gradient co-occurrence matrix based Uyghur document image retrieval method is proposed in this paper. 15 parameters of gray gradient co-occurrence matrix such as small gradient advantage, high gradient strengths, intensity in homogeneity etc are extracted separately, and document image features are matched with the characteristic distance classifier and the Euclidean distance classifier....
In this paper a new approach for Farsi font recognition is presented. In this approach using the Euclidean distance between spatial descriptors and gradient value in each point of boundary of some especial letters, font of a document image is recognized. To test this approach we constructed a dataset consisting of some letters in 20 widely used Farsi fonts and obtained recognition rate more than 94%...
