Patent ID: 8885030

Claim:
A device for tracking objects in a video stream, said device comprising one or more processors configured for: selecting video portions, comprising sequences of a predetermined object, from said video stream; tracking positions of said predetermined object in said video portions; creating video streams of predetermined objects, the one or more processors configured for creation of partial video streams as a function of tracked positions obtained from tracking positions of said predetermined objects, each said partial video stream representing one tracked predetermined object; composing said partial video streams of individual said tracked predetermined objects into an output video stream; wherein said tracking comprises: setting reference points representative of each said predetermined object in said tracked position; and associating predetermined polygonal shapes with said predetermined object in said tracked positions, starting from said reference points; and the associating predetermined polygonal shapes with said predetermined objects in said tracked positions comprises a linear approximation algorithm interpolating a reference sequence and comparing the reference sequence with said predetermined polygonal shapes.
