WebDec 31, 2009 · Here, we present a quality assessment method [most apparent distortion (MAD)], which attempts to explicitly model these two separate strategies. Local … WebMAD models both near-threshold distortions and appearance-based distortions. It employs different approaches for high-quality images (near-threshold distortions) and low quality images (supra-threshold distortion). These are combined using a non-linear model to a obtain final quality index.
