Window-Extent Tradeoffs in Inverse Dithering
  DOI :  10.2352/CIC.1998.6.1.art00052  Published OnlineJanuary 1998

A video-rate color inverse-dithering system based on edge-sensitive low-pass filtering is introduced. The twin requirements of low complexity and low memory necessitate tradeoffs in system design, especially in the extent of the processing window. Our investigation shows that a single-line window is sufficient for achieving good results. We also investigate whether the separate color channels (RGB) should be processed independently. Our study suggests that processing the color channels jointly does not provide significant benefits.
