Abstract
The invention is directed to real-time processing of video data. In some examples at least one image of the video data is processed utilizing reference data comprising reference image data of background within a region of interest and clutter image data indicative thereof, to determine a pixel deviation level of each pixel in the at least one image and generate pixel-deviation image data indicative thereof. The pixel-deviation image data is processed to enhance its tonal pixel distribution and generating enhanced image data, which is processed to determine a threshold level based on the tonal pixel distribution. A binary image map is then generated using the determined threshold level, the binary image map being indicative of the background and foreground components of the at least one image.
