Fast C Implementation of CVVDP Video Quality Metric from Cambridge University
By

Hot, fresh, and worth queueing round the block for.
Summary
fcvvdp is a fast C implementation of the CVVDP (Color Video Visual Difference Predictor) metric from the University of Cambridge. The implementation offers significant performance improvements over the original, using 91% less RAM, 88% fewer CPU cycles, and being almost 18% faster in wall clock time. While currently limited to single-threaded operation, it demonstrates ~15x more efficiency in user time compared to the multi-threaded original implementation.
