Math Upscale is not true AI super-resolution. It uses interpolation + sharpening with FFmpeg.wasm in your browser. It can improve look and size, but it does not invent true scene detail.

2) B&W Image Colorizer

This is an AI-style color tinting helper in the browser, not historical truth restoration. It can produce pleasing results, but exact real-world colors are not guaranteed.
