Fast Cross-Platform C/C++ Image Processing Libraries
What are some cross platform and high performance image libraries for image processing (resizing and finding the color/hue histograms). No gui needed. This is for C/C++.
So far I have looked in to
- OpenCV
- GIL as part of Boost
- DevIL
- CImg
My questions
- How's the performance of the ones I have listed above
- What are some other libraries
Your input much appreciated.
Solution 1:
OpenCV has quite good performance. It should be sufficient for most cases.
To improve performance, you can also use OpenCV together with Intel IPP, which is however a non-free commercial product. If OpenCV detects that IPP is installed it will use it where possible.
As a third option you can use IPP directly. IPP was designed with high performance (on Intel architectures) as a goal. It is optimized to use the intel SIMD instructions.
Solution 2:
imagemagick is quite popular.
Solution 3:
Don't forget to look at CxImage - I've used it professionally in globally deployed graphics intensive mobile phone applications, where it performed perfectly and it's so full of features. Do check it out!
