Abstract
A behavior recognition method includes extracting, by a computer, skeleton information including a plurality of joint positions for each frame of an image, calculating a first set of motion feature amounts from the skeleton information, calculating a plot position by plotting the first set of motion feature amounts on a feature amount space defined by a second set of motion feature amounts, the plot position being a position where the first set of motion feature amounts is plotted on the feature amount space, the feature amount space having a plurality of mapping areas in which respective ranges corresponding to predetermined higher-level behaviors to be recognized are mapped, and expanding, when a degree of divergence from a minimum distance to other distances among distances between the plot position and each of the plurality of mapping areas satisfies a predetermined criterion, a mapping area at the minimum distance from the plot position.
