Dither image processing
Webinterest of applying similar techniques to digital image processing, but that the theory devel-oped on this topic is relatively incomplete by comparison. The image processing community appears to be aware of dithered quantization, or \threshold modulation", but does not seem to be aware of how di erent dither signals can a ect the quantized signal. Dither is utilized in many different fields where digital processing and analysis are used. These uses include systems using digital signal processing, such as digital audio, digital video, digital photography, seismology, radar and weather forecasting systems. Quantization yields error. If that error is correlated to the … See more Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images.
