A system and method are disclosed for providing a gesture recognition system for recognizing gestures made by a moving subject within an image and performing an operation based on the semantic meaning of the gesture. A subject, such as a human being, enters the viewing field of a camera connected to a computer and performs a gesture, such as flapping of the arms. The gesture is then examined by the system one image frame at a time. Positional data is derived from the input frames and compared to data representing gestures already known to the system. The comparisons are done in real-time and the system can be trained to better recognize known gestures or to recognize new gestures. A frame of the input image containing the subject is obtained after a background image model has been created. An input frame is used to derive a frame data set that contains particular coordinates of the subject at a given moment in time. This series of frame data sets is examined to determine whether it conveys a gesture that is known to the system. If the subject gesture is recognizable to the system, an operation based on the semantic meaning of the gesture can be performed by a computer.

[ What is claimed is:] [1.] A computer-implemented method of storing and recognizing gestures made by a moving subject within an image, the method including:a) building a background model by obtaining at least one frame of an image;b) obtaining a data frame containing a subject performing part of a gesture;c) analyzing the data frame thereby determining particular coordinates of the subject at a particular time while the subject is performing the gesture;d) adding the particular coordinates to a frame data set;e) examining the particular coordinates such that the particular coordinates are compared to positional data making up a plurality of recognizable gestures, wherein a recognizable gesture is made up of at least one dimension such that the positional data describes dimensions of the recognized gesture;f) repeating b through e for a plurality of data frames; andg) determining whether the plurality of the data frames when examined in a particular sequence, conveys a subject 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.
