Method for rating areas in video frames
First Claim
1. A method for rating areas comprised in video frames included in a video signal, and comprising:
- (a) providing a video signal comprising a plurality of consecutive video frames;
(b) selecting a frame from among said plurality of consecutive video frames, being a selected frame, and identifying a first plurality of objects comprised in said selected frame;
(c) upon comparing said selected frame with one or more other of said plurality of consecutive frames, dividing a plurality of said objects into a second plurality of background objects and a third plurality of foreground objects;
(d) dividing at least one object from among said third plurality of foreground objects into one or more connected components, where the connected component comprises at least one group of pixels and wherein a change in each of the pixels comprised in said at least one group of pixels is associated with a change in each of the remaining pixels of said at least one group of pixels; and
(e) associating an interest level with said one or more connected components based upon a pre-determined set of criteria, thereby providing a rating of areas comprised within said video signal.

Abstract
A method is provided for rating areas in video frames. The method comprises: (a) providing a video signal comprising a plurality of consecutive video frames; (b) selecting a frame from among these frames and indentifying a first plurality of objects comprised in the selected frame; (c) upon comparing the selected frame with other frames, dividing the first plurality of the objects into a second plurality of background objects and a third plurality of foreground objects; (d) dividing objects of the third plurality of foreground objects into one or more connected components, where a connected component comprises group(s) of pixels wherein a change in each of these pixels is associated with a change in each of the remaining pixels of the respective group(s); and (e) associating an interest level with the connected components based upon a pre-determined set of criteria, thereby providing a rating of areas comprised within the video signal.

10. A non-transitory computer readable medium storing a computer program for executing a set of instructions by a computer system comprising one or more computer processors a process for rating areas comprised in video frames which are included in a video signal, the process comprising:
-
(a) selecting a frame from among a plurality of consecutive video frames comprised in a video signal provided, said frame being a selected frame; (b) identifying a first plurality of objects comprised in said selected frame; (c) upon comparing the selected frame with one or more of said plurality of consecutive video frames, deriving a second plurality of background objects and a third plurality of foreground objects; (d) dividing at least one object from among said third plurality of foreground objects into one or more connected components; and (e) associating an interest level with said one or more connected components based upon a pre-determined set of criteria, thereby providing a rating for areas comprised within said plurality of video frames. - View Dependent Claims (11, 12, 13)
