Abstract:
1. A method of performing computerized processing of image data comprising: analyzing, via a computer, first display information including pixel data indicative of pixel display on a graphical user interface; detecting one or more ramp steps in the pixel data assigning, in association with random number generation and/or threshold setting functionality, a carry possibility for a pixel adjacent the one or more ramp steps; and generating second display information including adjusted pixel data for pixels adjacent the ramp steps; wherein the second display information includes pixel values adjusted according to the carry possibility in one or both of the temporal domain and/or spatial domain; wherein the carry possibility is an adaptive carry possibility characterized in that carry possibilities for pixels adjacent the one or more ramp steps are accorded progressively smaller possibilities as a function of the pixel's increasing distance from the adjacent ramp step; wherein differing carry possibilities are assigned to pixels as a function of deviation from the one or more ramp steps; wherein, when deviation (dev) is characterized mathematically as (y where T
