Claim One:
1. An automated human action recognition system for automatically recognizing one or more actions of a human from 2D input image data representing a sequential series of input images of the human performing the one or more actions from the same viewpoint, each input image being represented by 2D image data, the system comprising: a computer memory system containing 2D reference image data representing a plurality of reference actions which a human may perform, wherein the 2D reference image data includes a plurality of linked sequences of key poses, including a linked sequence of key poses for each reference action, and for each reference action: each key pose within the linked sequence of key poses for the reference action consists essentially of 2D image data that is representative of a human figure performing the reference action at a selected point during the reference action; the timing of the selected points within the linked sequence of key poses for the reference action is based on changes in the position of the human figure during the performance of the reference action; and the linked sequence of key poses for the reference action uniquely distinguish it from the linked sequence of key poses for all of the other reference actions; and a computer processing system configured to determine which of the linked sequences best matches the 2D input image data.
