Show HN: Using 2D DFT, dithering, etc. to maximize eInk manga image quality

An author posted on Hacker News a project that applies a two‑dimensional discrete Fourier transform, dithering algorithms, and related image‑processing methods to enhance the visual fidelity of manga on e‑ink screens. The approach seeks to reduce banding and improve contrast while preserving the original artwork’s details, offering a potential workflow for readers who prefer high‑quality monochrome rendering on e‑readers.
