Is that an actual example of the clothing they are talking about?
"Look at all the babes, Err."
That would definitely mess up a vision system scanning for faces.
All of those green boxes are possible matches for a face.
The first part of a search would be to scan for an image that looks like a “face”. The second part would be to compare that image to a database, and try to match it based on measured points.
I’ve worked on industrial high speed vision image recognition system. They can be stupid fast in operation, IF they are set up to look for a specific target.
This would be the equivalent of a hundred people standing in a room with an image recognition camera, and one of the people holds up a “where’s waldo” poster to the camera. The software would choke on it.
How about a Che T-shirt?
