System and method for online processing of video images in real time
First Claim
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.

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.
