The detection of texts in video images is an important task towards automatic content-based information indexing and retrieval system. In this paper, we propose a texture-based method for text detection in complex video images. Taking advantage of the desirable characteristic of gray-scale invariance of local binary patterns (LBP), we apply a modified LBP operator to extract feature of texts. A polynomial...
Road intersections in aerial images could provide lots of geography information, and thus are very valuable for navigation systems, e.g. cruise missile or UAV (unmanned Aerial Vehicle) navigation system. However, there are few algorithms presented to exactly locate road intersections, and mostly the computational costs of them are very expensive, which can not meet the on-line processing requirement...
Virtual view synthesis is a key technology for future free viewpoint video and three-dimensional video applications. A novel asymmetric bidirectional view synthesis method is proposed for multi-view video plus depth based systems. An intermediate virtual view is synthesized based on two adjacent reference views, which are termed as the main view and the auxiliary view. The main view contains two-dimensional...
