Abstract
Halftone processes convert a graytone image represented by its spatial intensity distribution I(x,y) into a binary (quantized to two intensity levels) image B(x,y). Advantages of binary images are for example: the use of binary working hardware to display the image or reduced capacity to store or to transmit it. Different coding techniques as pulse density (PDM) and pulse width modulation (PWM) adapt the resulting binary images to special hardware conditions.
