1. A computerized system for real-time processing of video data, the system comprising a processor utility comprising: a reference data module configured and operable to provide reference data comprising reference image data of background within a region of interest and clutter image data indicative thereof; a pixel deviation calculator configured and operable to receive at least one image of said video data, and process said at least one image utilizing said background reference image data and said clutter image data to determine a pixel deviation level of each pixel in said at least one image and generate pixel-deviation image data indicative thereof; a filtering module configured and operable to enhance tonal pixel distribution in the pixel-deviation image data and generating enhanced image data; a binary image generator configured and operable to process the enhanced image data and determine a threshold level based on the tonal pixel distribution, and generate a binary image map being indicative of the background and foreground components of said at least one image.
