- W2022077174 abstract "As large-scale direct view TV screens such as LCD flat panels or plasma displays become more and more affordable, consumers not only expect to buy a ‘big screen’ but to also get ‘great picture quality’. To enjoy the big picture, its viewing distance is significantly reduced. Consequently, more artifacts related to digital compression techniques show above the threshold of visual detectability. The artifact that caught our attention can be noticed within uniform color patches. It presents itself as ‘color blobs’ or color pixel clustering. We analyze the artifact’s color characteristics in RGB and CIELAB color spaces and underline them by re-synthesizing an artificial color patch. To reduce the visibility of the artifact, we elaborate several linear methods, such as low pass filtering and additive white gaussian noise and verify, whether they could correct or mask the visible artifacts. From the huge list of nonlinear filter methods we analyze the effect of high frequency dithering and pixel shuffling, also based on the idea that spatial visual masking should dominate signal correction. By applying shuffling, we generate artificial high frequency components within the uniform color patch. As a result, the artifact characteristics change significantly and its visibility is strongly reduced." @default.
