Optimal Dither and Noise Shaping in Image Processing
A method for converting N-bit image data of a digital image into M-bit image data, in which N−M=K, K>0, is disclosed. The method is adapted to be used for dithering in an image processing system or a computer graphic system. For example, an N-bit red color value of ...
a. Dithering in digital image processing Dithering is a technique used in computer graphics to create the illusion of color depth in images with a limited color palette (color quantization). In a dithered image, colors not available in the palette are approximated by a diffusion of colore...

If the display controller supports multiple bits per pixel, it can use various techniques, such as PWM, in order to produce a pseudo-grayscale image. But, what if you have a monochrome-only display controller? With a sufficiently high pixel clock, can you use software on the application ...
There are already a number of neat applications (listed below) that can perform Atkinson dithering on source images. Today we’re releasing a neat little Processing sketch that takes video from your webcam and performs Atkinson dithering on it in real time, to produce live video continuously pro...
Floyd-Steinberg dithering is an image processing technique that reduces the number of colors in an image to a limited palette. In MATLAB, you can implement this algorithm by iterating through each pixel of the image and quantizing the color values based on the nearest palette color. The ...
Concept of Dithering - Learn about the concept of dithering in digital imaging and its significance in reducing color banding through noise and texture.
