We present a fast, non-iterative technique for producing grayscale images from error diiused and dithered halftones. The rst stage of the algorithm consists of a Gaussian l-ter and a median lter, while the second stage consists of a bandpass lter, a thresholding operation, and a median lter. The second stage enhances the rendering of edges in the inverse(More)
965 noise has become the major part of remaining noise after filtering, it is important to prevent this increase. The RDS is replaced by the IRDS filter which corrects the thermal noise increase. Total variances, including sensing-node amplifier noise and reset noise, can give us a good idea of the interest in using IRDS filter. Their variance calculation(More)
