Vibrance这个单词搜索翻译一般振动,抖动或者是响亮.活力,但是官方的词汇里还从来未出现过自然饱和度这个词,也不知道当时的Adobe中文翻译人员怎么会这样处理.但是我们看看PS对这个功能的解释: Vibrance: Adjusts the saturation so that clipping is minimized as colors approach full saturation. This setting changes the saturation of all l
无意中浏览一篇文章,中间提到了基于多尺度的图像的细节提升算法,尝试了一下,还是有一定的效果的,结合最近一直研究的SSE优化,把算法的步骤和优化过程分享给大家. 论文的全名是DARK IMAGE ENHANCEMENT BASED ON PAIRWISE TARGET CONTRAST AND MULTI-SCALE DETAIL BOOSTING,好像在百度上搜索不到,由于博客的空间不多了,这里就不上传了, 我贴出论文核心的字段. 论文的核心思想类似于Retinex,使用了三个尺度的高斯模糊,再
