Nevertheless, non-uniformity correction of the MCIS is still underexplored in the literature. In response to the growing demand for both excellent image quality and uniform illumination in wide FOV imaging systems, Soochow University researchers: Dr. Yiqun Ji, Dr. Chenxin Zeng, Dr. Fenli Tan, ...
Method for obtaining image correction coefficient, and method and system for correcting non-uniform image 图像校正系数的获取方法、非均匀图像校正方法及系统 patents-wipo Disclosed are a method and device for extracting an iris image under the condition of non-uniform illumination. 实施例公开了一种...
Color correctionImage fusionVariational methodsNon-uniform illumination images are of limited visibility due to under-exposure, over-exposure, or a combination of these two factors. Enhancing these images is a very challenging task in image processing. Although there are numerous enhancement methods to ...
