Quantization noise and the error diffusion algorithm
Olof Bryngdahl · Journal of Electronic Imaging · 1994
The error diffusion algorithm is a flexible and powerful procedure to quantize pictures and holograms. Its free parameters allow controlled transformation of the quantization noise. The influence of the object on the quantization noise is shown. A method is presented to modify the object before it is quantized to reduce the object-dependent component of the quantization noise.
