Our goal in this research is to find a good inverse halftoning algorithm that recovers gray-scale images from the scanned images. To this aim, we develop the printer and the scanner models and two types of reconstruction methods. In the first method, the reconstruction filter is derived directly from the scanned data and the ideal original gray-scale image. In the second method, the forward halftoning, the printing and the scanning processes are reversed one by one. Either approach seems to produce reasonably good results.
