WebThe Hilbert curve method is useful for processing images before display on devices that do not render individual pixels distinctly (like laser printers). This dithering method can give better results than the dithering usually done by the laser printers themselves. The -clump option alters the number of pixels in a clump. Typically a PGM image ...

WebAnother method, one that is easier to implement—especially in wideband receivers—is to inject a narrow-band dither signal outside the signal band of interest, as shown in Figure 6. Usually, no signal components are located in the frequency range near dc, so this low-frequency region is often used for such a dither signal. WebDithering Methods. Use nearest color matching.
