Dithering, also called Halftoning or Color Reduction, is the process of rendering an image on a display device with fewer colors than are in the image. Digital Image Processing: Some Special Techniques Dithering presents about it. | 5/14/2020 4:35:05 AM Duong Anh Duc - Digital Image Processing Digital Image Processing Some Special Techniques Dithering 5/14/2020 4:35:05 AM Duong Anh Duc - Digital Image Processing Dithering Dithering, also called Halftoning or Color Reduction, is the process of rendering an image on a display device with fewer colors than are in the image. (Mateus Pins and Hermann Hild) The number of different colors in an image or on a device is used called its Color Resolution. Dithering, also called Halftoning or Color Reduction, is the process of rendering an image on a display device with fewer colors than are in the image. The number of different colors in an image or on a device is used called its Color Resolution. The term 'resolution' means 'fineness' and is used to describe the level of detail in a digitally sampled signal. It is used most often in referring to the Spatial Resolution, which is the basic sampling rate for a digitized image. 5/14/2020 4:35:05 AM Duong Anh Duc - | 5/14/2020 5:31:15 AM Duong Anh Duc - Digital Image Processing Digital Image Processing Some Special Techniques Dithering 5/14/2020 5:31:15 AM Duong Anh Duc - Digital Image Processing Dithering Dithering, also called Halftoning or Color Reduction, is the process of rendering an image on a display device with fewer colors than are in the image.

This is what we will call 'dithering' and is the subject of this work. Dithering is a one-way operation. Once an image has been dithered, although it may look like a good reproduction of the original, information is permanently lost. Many image processing functions fail on dithered images.
