在地下城寻求邂逅是否搞错了什么 第四季 BDRip
Dungeon ni Deai o Motomeru no wa Machigatte Iru Darouka IV BDRip
ダンジョンに出会いを求めるのは間違っているだろうか IV BDRip

原盘画质较差。原生分辨率非常混乱，大部分素材为原生 900p；少部分素材分辨率较低，比如 800p、810p；还有一部分素材分辨率较高，分布在 900 至 1080 之间，比如 903、946、965、1080 等等。官方制作时的后期处理也是乱七八糟，有时锐化、有时模糊。以上问题导致部分线条有严重的锯齿和振铃。源还加了一层高强度动态噪点，产生了不少压缩瑕疵，少数暗场还有非常严重的色带。
The source quality is rather bad. The native resolution of materials is various: most of 900p, some lower as 800p/810p, some higher as 900p-1080p e.g. 903p/946p/965p/1080p. The post-production is also a mess, sometimes sharpening, sometimes blurring. Those all above make the lines with serious aliasing and ringing. On the other hand, the image is covered by high-density dynamic noise, resulting in many compression artifacts. Some dark scenes have heavy colour banding as well.

我们进行了逆向拉伸重构，并配合必要的分段和遮罩以处理不同分辨率的素材，辅以常规的抗锯齿和去振铃以清理残留的瑕疵。然后是自适应去色带、补偿性锐化。考虑到体积限制，我们进行了噪点层时域稳定，并配合亮度自适应降噪以控制码率。
To fix all these, we did rescaling with necessary scene-filtering and masking to separately process materials in different resolutions. We then applied the routine AA and de-ringing to clean up the remaining artifacts. This was followed by adaptive de-banding and compensatory sharpening. Given the size limitations, we performed grain stabilization and luminance-adaptive denoising to control the bit-rate.
