Digital Halftoning
Digital halftoning is the process of reproducing gray-scale
images in a bi-level display device. It employs a dithering
technique to minimize the extreme quantization effects involved.
We are working on new algorithms using space filling curves.
Our goal is to make possible high quality reproduction of digital images.
