Browser-based manga text erasure without an inpainting model

imgtranslator.com translates text inside images and redraws the translation in place, with OCR and translation handled on a server. The erasing step runs on a canvas in the browser, and the author deliberately avoided generative inpainting because it can silently alter non-text content such as prices or faces. The first hand-written pixel-rule eraser assumed text colour could be inferred from contrast with the strips above and below each box, which failed badly on manga. A second approach instead treats text as the colour that is common inside an OCR box but rare in a ring just outside it. Failures across 166 real uploads and 2,115 boxes were analysed, with the author noting that vertical manga columns were especially problematic.
