METHOD FOR SELECTING AN IMAGE FRAGMENT FOR TELEVISION COORDINATORS Russian patent published in 2008 - IPC H04N7/18 

FIELD: television engineering, in particular, method for selection of objects on complex underlying background, possible use for systems for automatic detection of coordinates of objects in television automatics.

SUBSTANCE: in accordance to the method, histogram processing threshold is optimized with the target of reaching minimal radius of compactness of binary image. For that purpose, a set of weighted radiuses of binary elements is computed and resulting compactness radius is compared to standard, which represents a radius of ideally compact figure, such as a circle with area equal to area of resulting binary image. Then, range of one of histograms is reduced or increased and compactness radius calculations are repeated until its value maximally approaches the standard value. Object coordinates shifting value is determined by scanning the area of object/background binary image with sliding strobe of object and by detection of position with the least compactness radius.

EFFECT: high selectivity of object image.
