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.
