- 1New image processing tricks aim to sharpen manga on eInk readers▼Show HN: Using 2D DFT, dithering, etc. to maximize eInk manga image quality
A developer has shared a technique combining 2D discrete Fourier transforms, dithering and related image processing methods to get the best possible manga rendering on eInk displays. The approach is integrated into an open-source Kindle Comic Converter tool, and the tech community is discussing how well the frequency-domain filtering and dithering translate to grayscale e-ink screens, which have limited contrast and refresh constraints.
