Video++ is a video and image processing library taking advantage of the C++14 standard to ease the writing of fast video and image processing applications. The idea behind Video++ performance is to generate via meta-programming the simplest code possible such that the compiler enable optimizations like loop vectorizing. Its main features are:

Generic N-dimentional image containers.
A growing set of image processing algorithms.
Zero-cost abstractions to easily write image processing algorithms for multicore SIMD CPU processors.
An embeded language to evalute image expressions.
