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++.

Answer 1

There is a simple and free open source cross-platform image processing library Simd. As follows from its description:

It provides many useful high performance algorithms for image processing such as: pixel format conversion, image scaling and filtration, extraction of statistic information from images, motion detection.

The algorithms are optimized with using of different SIMD CPU extensions: SSE, SSE2, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 and AVX-512 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC, NEON for ARM.
