The Simd Library is a free open source image processing library, designed for C and C++ programmers. 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, object detection (HAAR and LBP classifier cascades) and classification, neural network. The algorithms are optimized with using of different SIMD CPU extensions. In particular the library supports following CPU extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 and AVX-512 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC, NEON for ARM. ...

...Based on the Fast Structural Similarity index proposed by Chen and Bovik: http://live.ece.utexas.edu/publications/2011/chen_rtip_2011.pdf Implements the original, variance-based SSIM, Multi-Scale SSIM, Fast SSIM, 2, 3 and 4-Component Weighted SSIM, and Gradient Magnitude Similarity Deviation. Indexes may be customized by selecting image structure statistic (variance, gradient, shifted gradient, 2/3/4-component gradient of variance), structure scale (full, downsampled to 256 or multiscaled), pooling window type (Gaussian, Box, Box with downsampling, or unfiltered) and size, index stabilization (logical or by constants) and luminance index (Gaussian, Box, Box with downsampling or no luminance index).
