DiffImg是一个简单的图像比较工具，可用来比较相同尺寸的两个RGB图像，并提供两个图像的差异比较数据。采用C/C++开发并在GPLv2协议下授权。
DifffImg use OpenCV as backend so it can read and compare 8/16/24/32 bits images without problem but only single channel and RGB image has been take into account, so alpha channel isn't supported.
Because DiffImg is written with Qt, it runs on Windows and Linux (MacOSX isn't tested yet) and OS/2. It can read basic formats as BMP, PNG, JPG but also Tiff and OpenExR.
Features
Image difference display : a yellow/red mask can overlay the original/modified images.
Single/Dual panels mode.
Statistic computation: Mean error, RMS error and min/max are computed.
Several metrics can be used for computing image difference.
Histogram of error.
"Slideshow" : DiffImg can compare directory of image, so you can switch to the previous/next comparison if you have two folders with the same image list.
Supported files :DifffImg uses Qt plugins to load images, so by default it can read basic formats as BMP, PNG, JPG and OpenCV supported formats (Tiff, OpenExR).
Basic batch mode
Supported Plaforms
Windows XP, Vista, Seven (with provided installer)
Linux (with recompilation).
最新版本：2.0
