In this paper, a new method is proposed to provide a reliable and accurate algorithm to search and precisely find the center of a reference image in a set of video frames. By implementing algorithms such as SIFT and PCA-SIFT, some matched points are obtained. Some of these points are accurate, some of them are not strictly accurate and others are incorrect. As a result, registration process may be...
Script recognition is a necessary process before OCR algorithm in multilingual systems. In this paper, a novel method is proposed for identifying Farsi and Latin scripts in bilingual document using curvature scale space features. The proposed features are rotation and scale invariant and can be used to identify scripts with different fonts. We assumed that the bilingual scripts may have Farsi and...
