Fast Cross-Platform C/C++ Image Processing Libraries

Question

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.

Answer 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.
