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.

Abstract: A system for processing an image of a human face, the system including a data processing and analyzing utility including a high-pass filtering module outputting a high-pass signal indicative of edges or contours of the face in the input image data; at least one band-pass filtering module outputting a bandpass signal indicative of low-contrast slowly-varying qualitative features of the face; a low-pass filtering module outputting a low-pass signal in which low-contrast regions are smoothed and high-contrast regions are preserved; a feature computation module calculating a localized feature of the image for a plurality of pixels of the image; a strength computation module determining a localized operand using the localized feature to determine a strength of filters to be used in the high-pass, band-pass, and low-pass filtering modules at the pixels, and transmitting the localized operand to the filtering modules; at least one transformation module altering a portion of the high-pass, the bandpass, or the low-pa
