一、背景介绍最近有点忙过头了,抽离点时间对opencv上实现的,4个传统tonemap算法做了个简单整理记录。 二、TonemapDrago1、相关资料原始论文:Adaptive Logarithmic Mapping For Displaying High Contrast Scenes…
Syntax RGB = tonemap(HDR) RGB = tonemap(HDR,Name=Value)Description RGB = tonemap(HDR) converts the high dynamic range image HDR to a lower dynamic range image, RGB, suitable for display, using a process called tone mapping. Tone mapping is a technique used to approximate the appearance ...
Filmic tonemap(电影色调映射)是将HDR色域映射到LDR色域(D5里面就是Linear 到 sRGB)的优秀解决方案,由John Hable老哥发扬光大,是早已在VR和CR渲染器中提供的功能,希望D5早日在后期中加入这么重要的功能。 image1440×1195 129 KB 这位老哥在他的博客里面很详细的介绍了Filmic tonemap的原理,http://filmicworlds...
当我们关闭Tonemap 的时候,USE_GAMMA_ONLY 宏会被打开,直接做一个简单的gamma 矫正。 通过比较pow(0.4545) 和Tonemap 的结果,我们会发现,普通的Gamma矫正会曝光,其实是因为,pow 0.4545 之后,仍然会有超过1 的颜色。经过Tonemap 之后,颜色被映射到0-1的范围。没过曝的地方,颜色过度很自然。 上文Tonemap 使用...
Example: RGB = tonemap(HDR,AdjustLightness=[0.05 0.95]) adjusts the lightness of the rendered image such that pixel values between 0.05 and 0.95 linearly map to display values between 0 and 1. Before R2021a, use commas to separate each name and value, and enclose Name in quotes. Example...

tonemap Tonemapped Tone Mapping原是摄影学中的一个术语,因为打印相片所能表现的亮度范围不足以表现现实世界中的亮度域,而如果简单的将真实世界的整个亮度域线性压缩到照片所能表现的亮度域内,则会在明暗两端同时丢失很多细节,这显然不是所希望的效果,Tone Mapping就是为了克服这一情况而存在的,既然相片所能呈现的...
