Paper Abstract

To compensate for the imperfections of endoscopic mechanical structure and limitations of working space, in paper, a new approach based on recursive minimum-maximum method is proposed to enlarge images of medical electronic endoscopic. This method can be used repeatedly to realize 2n times image enlargement through optimizing the neighborhood information of the interesting pixels in adjustable windows. In order to ensure the best evaluation of the pixel, the algorithm criterion is presented to decide whether the pixel accept new value. Experimental results on applying the method to the endoscopic images are presented in this paper. The results demonstrate that the recursive minimum-maximum method for enlarging images can succeed in images blowing-up at the same time it preserves the fine details with rich edge-information.
