It looked like garbage at first. Then, after 16 hours of processing a single 3-second clip, the mosaic dissolved .
I re-ran the script on a redacted section of the video. The mosaic faded. Underneath the pixelation, written on the back of the identity document in the video, was a handwritten sticky note the subject had forgotten to remove. It said:
There are problems in tech that make you feel like a god. You write a three-line script, hit enter, and watch as efficiency skyrockets. Then, there are the other problems. The ones that live under your skin. The ones that wake you up at 3:00 AM in a cold sweat.
: Your title mentions "Reducing Mosaic." In the context of Japanese adult media, "mosaic" refers to the censorship overlays required by law. High-quality releases like those found on The Movie Database (TMDB) focus on "rich and dense" cinematography to compensate for these visual restrictions.
Traditionally, a mosaic is just pixelation. Blur a face, hide a license plate. Easy. But MIDV-231 introduced adaptive mosaicking. The block size changes depending on the movement of the document in the frame. One frame, the ID is clear. The next frame, it looks like a Lego brick. The next, it’s half-clear, half-censored.
