Claim:
Method for detecting and classifying an event occurred during motion actions of one or more subjects in an area, the occurrence or not of said event depending upon predetermined rules related to said motion and to mutual positions of said subjects in a predetermined time instant, the method comprising: acquiring a plurality of digital images in sequence of said area during the progress of said actions; extracting a reference image by identifying static points in said images based on average and variance values for each dot in said images and by scrolling a time window in multiple iterations and storing the average and variance values related to statistical points of the whole time window over each iteration; processing each image of said plurality of images for extracting first features apt to identify each one of said subjects and second features apt to determine an instantaneous position of each one of said subjects within said area; classifying said subjects based upon said first and/or second features; and evaluating the occurrence of said event, by verifying said predetermined rules based upon said first and second features and upon the result of said classification.
