METHOD AND DEVICE FOR DETECTING AND TRACKING NON-RIGID OBJECTS IN MOVEMENT, IN REAL TIME, IN A VIDEO STREAM, ENABLING A USER TO INTERACT WITH A COMPUTER SYSTEM

摘要

PURPOSE: A method and device are provided to help a user and a software application to interact with each other by detecting and tracing atypical objects moving in a video stream in real time. CONSTITUTION: One or more first images are received from an image sensor. One or more first regions of interest are identified within the first image. The one or more first regions of interest correspond to the one or more first images. One or more second images are received from the image sensor. One or more second regions of interest are identified within the second image. The one or more second regions of interest correspond to the one or more second images. A device compares the first regions of interest and the seconds of interest and traces interest points(440). The device determines movement of one or more objects from an interest mask(445). The device calculates new location of the first and second regions of interest. The device estimates a specific interaction according to parameters(470).
