Abstract:
A system for processing video signal information to identify those pixels associated with a moving object in the presence of platform and/or sensor pointing induced motion. Frame differencing with self-adjusting noise thresholds is implemented to detect pixels associated with objects that are in motion with respect to the background and a field-by-field motion pixel map of pixels associated with the moving object is generated. A two (2) step pixel grouping process is used where the first pass runs in real-time as the video signal is received and writes the links between pixel groups into entries in a table. The second pass operates on a smaller set of link data and only needs to reorder entries in the table.

Claim (Index 1):
A method of detecting a moving object in an image signal, the method comprising:\n providing, with a digital video camera, an image signal including a plurality of sequential image frames of a plurality of pixels (P); providing, by a first processor coupled to the digital video camera, a motion map including, for each pixel (P) in the image frame, a corresponding motion map pixel (MP) set to either a first motion value (FMV) or a second motion value (SMV) indicating that the pixel (P) is associated or is not associated, respectively, with an object in the image frame that is in motion with respect to a background; and by a second processor coupled to the first processor, for each image frame:\n assigning a group count value (GCV) to each motion map pixel (MP) as a function of the motion values of adjacent motion map pixels; \n maintaining an indexed grouping table comprising outer pixel coordinates for a boundary about each group of pixels having a same group count value (GCV) and information representing two groups of pixels having different group count values adjacent to one another; \n determining if two different groups of pixels having different group count values are adjacent to one another by comparing the group count value (GCV) for each respective motion map pixel MP to the GCVs of two adjacent motion map pixels and, if so determined, updating the outer pixel coordinates of the group count value for the adjacent motion map pixel in the indexed grouping table; \n maintaining a multiple link table including information identifying a motion map pixel having a group count value GCV adjacent to two other motion map pixels each having a different group count value GCV; \n traversing the indexed grouping table and the multiple link table and determining boundary pixel coordinates for a boundary that encompasses two or more adjacent groups of pixels having different group count values, the boundary pixel coordinates identifying the moving object in the image signal; and \n forwarding the boundary pixel coordinates to an object tracking system.
