原盘画质尚可,主要问题是线条有低分辨率拉伸带来的锯齿和晕轮,以及背景素材原生带有的锯齿。我们采用逆向拉伸重构,并配合常规抗锯齿和去晕轮来处理线条。原盘有一层极厚的噪点,因此基本没有色带,我们在保证画风的前提下,进行自适应降噪以控制码率。
The image quality of the original source is acceptable while the main problem is that the lines feature aliasing and ringing caused by low-resolution upscaling and the background images show aliasing at native resolution. We used descaling and reconstruction, along with regular anti-aliasing and de-ringing for the lines. The original source has a very thick layer of noise, so there is basically no banding. On the premise of ensuring the style of the picture, we performed adaptive denoising to control the bit rate.
