Abstract: A technique is presented for quantizing pixels of an image using Sigma Delta quantization. In one aspect, pixel values for an image are segmented into columns of pixel values; and for each column in the matrix, pixel values of a given column are quantized using sigma delta modulation. The pixel values in a given column are preferably quantized as a whole, thereby minimizing accumulated quantization error from a starting pixel value in the given column to a current pixel value in the given column. In another aspect, the pixels of an image are quantized using a 2D generalization of Sigma Delta modulation.
