20. A computer-implemented system for storing and recognizing gestures made by a moving subject within an image, the system comprising: an image modeller for creating a background model by examining a plurality of frames of an input image that does not contain a subject; a frame capturer for obtaining a data frame containing the subject performing part of a subject gesture; a frame analyzer for analyzing the data frame thereby determining relevant coordinates of the subject at a particular time while the subject is performing the subject gesture; a data set creator for creating a frame data set by collecting the relevant coordinates; a data set analyzer for examining the particular coordinates in the frame data set such that the particular coordinates are compared to positional data making up a plurality of recognizable gestures, wherein each recognizable gesture is made up of at least one dimension such that the positional data describes dimensions of the recognized gesture; and a gesture recognizer for determining whether a plurality of the data frames, wherein a data frame is represented by a frame data set, when examined in a particular sequence, conveys a gesture by the subject that resembles a recognizable gesture, thereby causing an operation based on a predetermined meaning of the recognizable gesture be performed by a computer.

A system as recited in claim 20 wherein the gesture recognizer further comprises a data comparator for comparing the frame data set to positional data corresponding to a dimension of a recognizable gesture.
