Ask HN: What camera apps exist that can blur faces securely? (re: Minneapolis)

Blurring just leaks information unnecessarily. We should go beyond blurring. In fact we could go beyond blacking out with bounding boxes too; we could use some kind of Mask CNN to segment the boundaries of people's silhouette, and then black those out.

This is what I would imagine it would need to look like:

[video input] -> [frames]

per frame:

[frame] -> run thru a person detection segmentation nn -> output an outline mask for the frame

fill in the outline mask in the frame with eg. black

reconstitute [set of frames] -> [output video]

Why are you looking to blur faces? I'm just wondering what the connection is to Minneapolis.
