What is the best dithering algorithm?

Floyd-Steinberg dithering is easily the most well-known error diffusion algorithm. It provides reasonably good quality, while only requiring a single forward array (a one-dimensional array the width of the image, which stores the error values pushed to the next row).

What is dithering technique?

In computer graphics, dithering is an image processing operation used to create the illusion of color depth in images with a limited color palette. Colors not available in the palette are approximated by a diffusion of colored pixels from within the available palette.

Is dithering still used?

Especially once you take into consideration listening volumes, limits of human hearing, and the dynamic range of most musical performances. There's a reason we say that CD-quality audio is still great. Dithering is still an important mastering technique in the modern music age.

What is a dithering effect?

Dithering is the process of defining gradations of gray or color shades in a 2-D graphic by varying the gray or color shades in the neighboring pixels. Dithering creates a halftone effect, but gives less resolution as shown in Figure 99 on the right. NOTE Dithering currently works only for 2-D images.
