Hakata Tonkotsu Ramens is such a financially embarrassed anime. Signs of underfunding can be seen throughout its production, and the Blu-ray is no exception: dreadful aliasing is everywhere, accompanied by unpredictable recurrence of fuzzy lines. These have contributed to an unforgettable "hard-up" image style overall.
We treated the all-time aliasing with a conservative anti-aliasing filter aiming for minimal side effects on the original line art. Adaptive de-noising and compensatory sharpening were then used to improve visual experience and restore some sharpness lost during the processing. On top of these, the encoding parameters were further adjusted to tackle slight colour banding in widely present dark scenes.
