Abstract: A method and system for estimating continuous tone values associated with input pixels in a color image are provided. The method includes receiving binarized halftone image data representing a color image, wherein the color image has a plurality of input pixels; and estimating the continuous tone values associated with each of the input pixels by: establishing a window comprising a pixel of interest and neighboring pixels in the binarized halftone image data, wherein the window comprises a plurality of sub-windows and wherein each sub-window has a plurality of predetermined number of rows and columns of pixels; and processing the binarized halftone image data in both a process direction and a cross-process direction using the window such that the processing is performed for one of the pixels in each of the rows within the sub-window and the processing is skipped for the remaining pixels in that row of that sub-window.
