This article describes a technique for vertically filtering image data. The technique can be used in conjunction with horizontal thresholding to provide one pass thresholding of luminance data in an image processing system. The vertical filter removes transition pels associated with horizontal lines, removes noise and improves vertical correlation of luminance levels.
