Abstract
A method for distinguishing non-input contact with a touch-sensitive user input device includes converting an input frame from the touch-sensitive user input device to an input luminance frame; and filtering the input luminance frame, based on a base luminance frame, using a Wronskian function, the Wronskian function producing a filtered luminance frame, the filtered luminance frame distinguishing input contact from non-input contact with the touch-sensitive user input device.
