Simd

Simd is an open-source image processing library created to help C and C++ programmers. It includes a number of high-performance image processing algorithms that are optimized using various SIMD CPU extensions.
Naturally, this package is only intended to be used by experienced developers who wish to use the library in order to enhance their software.
Simd comes equipped with numerous algorithms indented to help with various operations related to image processing, such as pixel format conversion, extraction of statistic information from pictures, image scaling and filtration, motion detection, object detection classification and neural network.
The included algorithms have been optimized using several SIMD CPU extensions. To be more specific, the library offers support for the following CPU extensions: SSE, SSE2, SSE3, SSE4.1, SSE4.2, SSSE3, AVX and AVX2 (for x86/x64), VMX (Altivec) and VSX (Power7) for PowerPC, as well as NEON for ARM.
Simd offers helpful C++ classes and functions in order to facilitate access to the C API. The library also offers support for dynamic and static linking.
The downloadable package incorporates all the components required by software developers, and users can also take advantage of the documentation that is included in the archive. It contains descriptions of all the classes and functions of the Simd library.
