What set of test images? https://www.androidpolice.com/wp-content/uploads/2020/06/04/signal-face-blur-b.png https://www.androidpolice.com/wp-content/uploads/2020/06/04/... is blurred by Signal. Suppose that you have all the photos that have been posted to Facebook, and that both of those women are on Facebook, and lastly that you have resources enough to run all of those through the Signal code. How would you match those other photos to the blurred part of this one?
