Cassandra - POMDPs

Anthony Cassandra. "A Survey of POMDP Applications." Presented at the AAAI Fall Symposium, 1998. http://pomdp.com/pomdp/papers/index.shtml, 11 Feb, 2008.

Summary

Not much to say about gesture recognition, which is not surprising since POMDPs are used for artificial intelligence in the area of planning. Think of a robot that has a goal and only a limited visual range (can't see behind obstructions, etc.). A POMDP might be used in this situation to evaluate different actions to take based on the current state of things.

The paper does mention machine vision and gesture recognition. The context here is that the computer uses a POMDP to focus a camera and a fovea (high resolution area for fine-grained vision) on facial expressions, hand movements, etc. The fovea is important because it is limited, and the areas outside it either have a much lower resolution (to reduce computational burden) or cannot be seen at all (outside the FOV).

Discussion

I really don't think POMDPs can be used for our purposes in gesture recognition.

However, this is a nice paper if you want examples of how POMDPs can be used in multiple domains.

That is all.
