The system, method, and program of the invention captures actual physical gestures made by a participant during a chat room or instant messaging session or other real time communication session between participants over a network and automatically transmits a representation of the gestures to the other participants. Image processing software analyzes successive video images, received as input from a video camera, for an actual physical gesture made by a participant. When a physical gesture is analyzed as being made, the state of the gesture is also determined. The state of the gesture identifies whether it is a first occurrence of the gesture or a subsequent occurrence. An action, and a parameter for the action, is determined for the gesture and the particular state of the gesture. A command to the API of the communication software, such as chat room software, is automatically generated which transmits a representation of the gesture to the participants through the communication software.

This invention proposes an identification system for license plates captured in low-quality motion video, such as accidental footage from security cameras, amateur video, cell phones, etc, including situations when the license plate number is completely unreadable. This is done by dividing the surface of the license plate into a pattern of segments assigned to a number of groups, each group possessing unique optical properties such as shading, reflectivity, IR absorption, etc. Taking advantage of the the varied light response among the segment groups, the pattern can encode identifying information, e.g. a binary sequence, which helps identify the vehicle. Using image processing software, this information can be decoded from low-quality video footage via an analysis of temporally correlated luminance levels. The system thus allows the identification of vehicles captured accidentally and under poor lighting conditions, as in the case of a security camera in a convenience store capturing the image of a vehicle fleeing a nearby crime scene.
