The visible and ultraviolet images are adjusted on a sliding 401x401 window by changing the center pixel of the sliding window so that the width and mean within the window is similar across the image. The visible and ultraviolet images each have three color separations, which are added together before being processed and combined in pseudocolor. Yes Adjustable over a sliding window. Variable enhancement 1.2 Archie 1.2, otsumask, pseudomask The differences between the visibility of the erased characters in ultraviolet and visible illumination are emphasized using pseudocolor.
