>> tracking movement habits through the store

My understanding is that was a passing fad a few years ago. It was hyped by some startups but commercial users found it less than helpful compared to traditional metrics. I met a grocery store consultant (a real job) at a security conference. He said they used cameras to deal with traffic issues (even load between aisles) and predict cashier/customer ratios. They had abandoned the face/eye-tracking tech. Eye-level shelf space is better. They don't need an algorithm to keep telling them that.

They don't need CV for this. They can use beacons embedded in smart devices to tell which part of the building you're in. Worked with one of these guys.

They need cameras for theft. Tossing a person detecting algorithm on top is basically free (especially if you don't need it to do fancy things like track faces).
