原生分辨率 719.7,画面偏糊,画质不佳。主要瑕疵是拉伸造成的锯齿和振铃,以及不良编码下的烂噪和色带。处理:逆向拉升重构、抗锯齿、去振铃、去色带、自适应降噪。部分场景的像素排列特效遮盖了瑕疵,而且天然抗压缩,因此画质较好,我们仅做了降噪。 The source's native resolution is 719.7, with blurry images and poor quality. The primary artifacts are the aliasing and ringing attributable to upscaling, as well as the grain blocking and banding due to defective encoding. Our pre-processing is descaling and reconstruction, anti-aliasing, de-ringing, de-banding, and adaptive denoising. Pixel-alignment effects in partial scenes conceal the artifacts and resist compression spontaneously withal, which results in good image quality and consequently denoising was solely performed.
