Abstract
Examples of methods and apparatuses for improving subjective video quality of a video signal are described herein. An example apparatus may include an encoder. The encoder may be configured to receive a video signal and to generate a saliency score for a macroblock of the video signal. The encoder may further be configured to adjust a quantization parameter for the macroblock of the video signal based, at least in part, on the respective saliency score for the macroblock of the video signal.
