                         using dispersed-dot ordered dithering algorithms. The proposed 
                         algorithm uses a simple set of linear filters combined with a 
                         stochastic model in order to predict the best intensity values for 
                         the binary image pixels. The algorithm produces images with a 
                         better perceptual quality than the available algorithms in the 
                         literature, preserving most of the fine details of the original 
                         gray-level image. It has a high performance, which can be further 
                         improved with the use of parallelization techniques.",
