Although widely studied for many years, colour quantisation remains a practical problem in image processing. Unlike previous works where the image can only be quantised after the ...
This paper presents an efficient method for the estimation and recovering from nonlinear or local geometrical distortions, such as the random bending attack and restricted project...
Error diffusion halftoning is a popular method of producing frequency modulated (FM)halftones. In FM halftoning the dot size and shape is fixed (equal to one pixel) and the dot fr...
