原盘总体画质一般,问题集中在线条上。本片线条表现出断线的美术风格,并且伴有低分辨率拉伸的痕迹与轻度的晕轮。我们采用逆向拉伸重构来处理,同时避免使用其他抗锯齿手段,尽量维持原本的断线画风。本片色度平面的质量非常糟糕,有着 Lerche 公司祖传的超强色度锯齿,这让本就断线的线条显得更加奇怪。我们使用一些高级神经网络滤镜来修复色度锯齿。原盘平面质量尚可,因此我们只使用了常规的自适应降噪和保底的去色带处理。
The source quality is not very good, with artifacts focusing on the lines. The lines feature a distinct dashed-line art style and are accompanied by slight haloing as well as other artifacts caused by low-resolution upscaling. We descaled and reconstructed the source without any other AA processing to maintain the dashed-line style as we can. The chroma planes are also bothering us a lot because of the traditional horrible chroma aliasing made by Lerche. This makes the already dashed lines look even stranger. We adopted several advanced neural network filters to fix the chroma aliasing. As for the flat areas, the quality is better than average, so we only applied routine adaptive denoising and preventive de-banding.
