Video Quality Metrics

Video quality metrics, reference implementation in python, with GPU optimizations and C versions as time permits.

Example

Run the demo/jpg_demo.py script, which will compress lena.png with JPEG at every quality setting 0-100, and plot all metric values vs quality setting and vs file size.
