GLSL CFL Prediction

This repository contains GLSL shaders for Chroma from Luma prediction, implementing chroma upscaling based on a closed least squares solution for linear regression. Predictions are mixed with a normal resampling filter and smoothed with a bilateral filter. Settings control which regressions are used and the smoothing step, and a lite variant offers better performance at some quality cost.
