A lightweight ML pipeline for blind real‑time video quality assessment runs on end devices and claims near state‑of‑the‑art correlation with human mean opinion scores by trading a few percent of accuracy for huge efficiency gains. It extracts DCT‑based spatial features, optional 3D spatio‑temporal cubes for motion, applies a partitioned MSE feature selection and a regressor, yielding GreenBIQA/GreenBBQA models that are about 50x smaller and ~500–700x less compute than top deep nets, but still mispredict attention‑focused edge cases.
