International ClassG06F 003/14AbstractA method for labeling the pixels within a selected visual area of at least one image frame containing that visual area from a sequence of image frames stored in memory and operative to be displayed on an interactive display so that a user may subsequently select the selected visual area on a pixel accurate, frame accurate basis. To label the selected visual area within an image frame, the scene within that image frame is segmented to identify the selected visual area, each pixel within that selected visual area is then labeled with an area identifier which is unique to that selected visual area, and the pixels containing the area identifiers are mapped into an item buffer. The item buffer is then compressed and stored within a labeled portion of memory linked with the stored frame image from which the item buffer was derived. When a user subsequently selects a pixel within any frame image of the sequence of frame images the pixel is decompressed within the labeled portion of memory corresponding to the pixel in the selected frame image to determine the area identifier for the selected pixel. This area identifier is then used for a number of purposes, such as to identify an area within the frame image corresponding to the selected pixel, or to cause some action related to the selected pixel to be performed.Other References
