This paper presents a novel approach for matching 2D points between a video projector and a digital camera. Our method is motivated by camera-projector applications for which the projected image needs to be warped to prevent geometric distortion. Since the warping process often needs geometric information on the 3D scene that can only be obtained from triangulation, we propose a technique for matching...
Two kinds of word processing templates are presented on CNN's theory in image- processing. The first template can change black words into arbitrary gray-scale value g with the white background color unchanged. The second template can change white background color into arbitrary gray-scale value g with the black word unchanged. At the same time, the robustness area and computer simulation are given.
Automatic video-text extraction is an important field in video content comprehension. In this paper, a robust video-text extraction method is presented which can automatically extract horizontally aligned text with different languages. First, an unsupervised paradigm based on Haar wavelets is applied to obtain candidate text region. Second, the traversing line with its aptitude spectrum is introduced...
