Video scene text contains semantic information and thus can contribute significantly to video indexing and summarization. However, most of the previous approaches to detecting scene text from videos experience difficulties in handling texts with various character size and text alignments. In this paper, we propose a novel algorithm of scene text detection and localization in video. Based on our observation...
Video text provides precise and meaningful information about video content. Video text extraction is a crucial step to retrieve video text characters. Most of papers perform video text extraction in a whole text row. Compared with whole text row extraction, single character extraction can achieve higher accuracy because the background of single character is relatively simple. However, character segmentation...
A common form of serious defect in video is pixel-shift. It is caused by the consecutive pixels loss introduced by video transmission systems. Pixel-shift means a large amount of pixel shifts one by one due to a small quantity of image data loss. The damaged region in affected frame is usually large, and thus the visual effect is often very disturbing. So far there is no method of automatically treating...
