The general-purpose image enhancement algorithm which raises the visual recognition of detail of the digital image

摘要

Topic Gradation adjustment of the picture/revision is simplified.Solutions Filtering doing the digital image, you obtain the local mean value to which every each pixel value of the picture corresponds (10). The picture is done, small filter radius weight using the conical type filter whose it is desirable to attach, for central pixel value of the possessing and radius, filtering. Using local mean value, from shadow function and the highlight function which are selected you obtain the respective shadow value and the value of highlight (11). The respective gradation function is guided from shadow value and highlight value of each pixel (12). Each pixel value of the picture, following to shadow gradation function and the highlight gradation function which are guided, rimatsupu it is done (13). Gradation the picture which is revised, until you can obtain the picture quality of desire, adjusts the parameter of shadow function and highlight function and repeatedly can revise by rimatsupu doing the graphics data, (14,15).
