论文摘要
本文提出了一种新的方法，用于改善补偿小波变换的低通带的视觉质量。高质量的低通带非常重要，因为然后可以用作原始信号的缩小版本。为了使转换适应信号，可以将补偿方法直接实施到转换中。我们通过通过重建方法处理未连接的像素来提出改善基于块运动补偿的反转。我们获得了更好的主观视觉质量，而无限损失编码的最多可节省多达2.6％的位。
This paper presents a new approach for improving the visual quality of the lowpass band of a compensated wavelet transform. A high quality of the lowpass band is very important as it can then be used as a downscaled version of the original signal. To adapt the transform to the signal, compensation methods can be implemented directly into the transform. We propose an improved inversion of the block-based motion compensation by processing unconnected pixels by a reconstruction method. We obtain a better subjective visual quality while furthermore saving up to 2.6% of bits for lossless coding.
