Abstract:
1. A method for processing digital images, comprising: converting an image to a two-dimensional array, wherein the two-dimensional array comprises one or more rows of pixels, and wherein each row of pixels comprises one or more row sections; computing a mean intensity of a row of pixels; computing a mean intensity of a row section of the row of pixels; if the mean intensity of the row section is greater than the mean intensity of the row of pixels, processing the pixels in the row section according to a first method; if the mean intensity of the row section is less than the mean intensity of the row of pixels, processing the pixels in the row section according to a second method; and wherein each of the first method and the second method comprises comparing the mean intensity of the row of pixels to a value computed as a function of a non-zero percentage threshold and an intensity of a pixel in the row section.
