Boolean complement methods and systems for video image processing a region of interest

An image-processing method, system and program-product. Data indicative of a video image displayable with a display device associated with a data-processing apparatus can be scanned. At least one region of non-interest among the data can be identified, in response to compiling the data. Thereafter, at least one region of interest associated with the video image can be designed, such that the region of interest is equivalent to the data indicative of the video image minus the region of non-interest, thereby permitting the region of interest to be defined for focusing image-processing operations thereof upon the video image. The region of interest can comprise a geometrically regular shape or an irregular shape.
