[Bug] Obfuscation Blur Area #27
Description
Device: Pixel 8 Pro
App Version 3.5.4 installed from Google Play Store on 2026-01-06
The area of the face that gets obfuscated does not complete cover a face, and potentially leaves recognizable characteristics in view. This looks to me like a scaling issue, where the obfuscated portion may be looking at a stretched/square version of the image and not accounting for a difference is length or width, so the actual area that gets obfuscated is "squished" vertically (or perhaps stretched horizontally) and doesn't completely cover the intended area. From a straight on shot of someone's face, this does seem to cover the eyes in my short experience, but leaves the mouth, hairline, and other distinguishing features visible. The bigger issue is when a photo is taken from slightly below, angling the face upwards and causing the eyes to still be visible.
Sorry if that doesn't make sense, here's some examples that should make it clear.
Image 1 is a stock photo of someones face from below, as I didn't want to post my own. Sorry for the poor quality, it's a picture of a picture, but you can see that the intended blur area (autodetected) covers the entire face.
Image 2 is the results of applying that blur. You can see that, rather than it being a tall oval that roughly matches the intended square, we get a wide oval that leaves the eyes completely visible.
Image 3 is an example just to show that this also occurs on manually selected areas. I took a picture of a square floor tile and selected the entire center tile, corner to corner, to make a square area that should be obfuscated. However, the result is that only the center half of the tile is obfuscated, and the top and bottom 1/4 or so isn't.
