METHOD AND SYSTEM OF GENERATING SALIENCY MAP USING GRAPHICS HARDWARE AND PROGRAMMABLE SHADER AND RECORDING MEDIUM THEREWITH

摘要

A projecting map generating method using graphics hardware and a programmable shader, a system thereof and a recording medium in which the method is recorded are provided to generate a projecting map about a 2D image, a 3D image and video in real time, thereby finding a degree that a pixel is outstanding. Each image to which an original image reflects each feature is extracted from the original image by using a programmable shader in graphics hardware(S620). Each mipmap texture corresponding to the extracted each image is generated(S630). A center-surround difference operation is performed about each mipmap texture. Each contrast image corresponding to each extracted image is generated by using the programmable shader(S640). The contrasting images are linearly combined. A projecting map is generated by using the programmable shader(S650).
