This paper discusses a method to extract character strings from scene images. In this method, the Canny edge detector is first applied to a scene image, and the binary edge image is then obtained. Next, small edge elements are separated from large edge elements because edge elements from characters are much smaller than edge elements from non-character objects such as signboards etc. However, many...

An automatic fringe counter for the equally tilting fringe of Michelson interferometer is designed by CCD and image processing technologies. This system can identify the center of equal tilting interferogram automatically in different degrees of illumination intensity, then draw a curve which shows the variation of the central intensity for every frame, at last count the integer and fractional fringes...
Tactile graphics are images that use raised surface so that a visually impaired person can feel them. Tactile graphics are necessary to visually impaired students when they study mathematics and science. Since producing tactile graphics are not simple task, an intelligent computer-aided system for assisting the production of tactile graphics is needed. Mathematical graph recognition from printed materials...
