video measurement of resident-on-resident physical aggression in nursing homes
Automated detection of aggressive behaviors captured in continuously recorded nursing home video can increase the accuracy of those reported by subjects and caregivers. We implement a detection algorithm based on the extraction of features as local binary motion descriptors, and apply a novel clustering algorithm to merge similar LBMD's into a video codebook, and build recognizers to classify aggressive from non-aggressive behaviors. This facilitates clinical investigation into this difficult to measure low frequency but high impact behavior.
