Halftoning is a technique for changing multi-tone images into two-tone binary images, which look like the original multi-tone images when viewed from a distance.

La tecnica de halftoning es utilizada en la vida cotidiana, ya que en el proceso de impresion y despliegue en pantalla, todas las imagenes se representan en forma de halftone; ademas de esta gran utilidad, la tecnica de haftoning esta siendo aplicada recientemente en varios campos, tales como la estenografia, la criptografia [2], la compresion de imagenes y video [3], y la autenticacion de imagenes [4], etc.
Esta organizado de tal modo que es posible seguir la evolucion del metodo halftoning y proporcionar una comparacion numerica de los metodos desde el punto de vista de la calidad y complejidad computacional.
Design of Tone-Dependent Color-Error Diffusion Halftoning Systems.
A blue noise pattern consists of dots suitable for halftoning purposes that are generated from uniform, seemingly random electronic "noise," but with the lower frequencies attenuated.
Parker said that the "low spatial frequencies correspond to big clumps that are visually displeasing" - the reason for the frequency filtering and hence the name for the halftoning mask.
The Blue Noise Mask is the first halftoning method to combine high quality with virtually instantaneous halftoning.
Epson's new AcuPhoto halftoning module on the driver uses advanced error diffusion technology for the halftoning process, enabling high- quality output that maximizes 1440 dpi resolution capabilities.
This balanced system of advanced technologies - Micro Piezo print head, QuickDry inks, media, AcuPhoto halftoning and printer driver - makes the astounding 1440 dpi color ink jet printers being announced Monday another winning first from Epson.
