A friend is working on a sleep study for their university. As part of the study, they place night-vision camcorders in children's rooms and have to monitor how often they wake up, call out for their caregiver, etc.

Right now, they are forced to watch 8-12 hours of video, most of which can be ignored since the child is sleeping most of the time. They'd like to have software do much of the menial work for them.

Does anyone know of any software that can strip out the "boring"/consistent parts where the child is sleeping and only mark pieces of video that are different than the rest of the video?
