Abstract: Systems and Methods disclosed for measuring a similarity between the input and the output of computing systems and communications channels. Techniques disclosed provide for low complexity prediction method of a perceptual video quality (PVQ) score, which may be used to design and tune performance of the computing systems and communications channels.

Abstract: A method includes sampling a common signal over a plurality of iterations, concatenating the sampled iterations, summing samples of the concatenated iterations within a window of a predetermined sample width, at each of a plurality of window positions along the concatenated iterations, and estimating noise of the common signal from the summed sample values at the window positions.

Abstract translation: 一种方法包括在多个迭代中对公共信号进行采样，将采样的迭代级联，在预定采样宽度的窗口内的级联迭代的样本在沿着级联迭代的多个窗口位置的每一个处求和，估计噪声 来自窗口位置处求和样本值的公共信号。
