Most commonly mislabeled behavior

The memory problem was solved by saving and clearing the workspace after work on a specific clip is done, unfortunately this makes the code run a bit slower (5+ hrs). For now, we'll only be using a subset of the whole data set; set00-set003. One of the most commonly mislabeled behaviors using the cuboids code is grooming, it's most often labeled as exploring. Grooming is characterized by the movement of the mouse's paws across its face or its face across its legs while the mouse stays in the same place. Drinking is also commonly mislabeled as exploring. We believe the main difference between these two behaviors is the movement of the mouse from one place to another. By keeping track of where cuboids are detected and incorporating that data into the behavior descriptor, we believe we can increase the accuracy of these behaviors.

The following videos show the cuboids as they're detected by the response function.
(still waiting for processing by google video)

Here we have a sample clip for grooming where the mouse stays in the same spot and mostly just moves his paws and face:
