Tiivistelmä

Downsampling applied to texture views prior to encoding can increase the subjective quality of decoded video. In our study, we show that spatial resolution selection based on traditional pixel-based distortion metrics, such as Mean Square Error (MSE) is weakly correlated with the resolution selection based on subjective quality of coded video. To overcome this problem, we propose a novel frequency-based distortion metric which is shown to resemble subjective quality of coded video more accurately compared to conventionally used MSE-based metric.
