r1968 r1971 34 34 35 35 <p> The idea behind error diffusion is to compute the error caused by 36 thresholding a given pixel and propagate it to neighbour pixels to 36 thresholding a given pixel and propagate it to neighbour pixels to 37 37 compensate for the average intensity loss or gain. It is based upon the 38 38 assumption that a slightly out-of-place pixel causes little visual harm. … … 45 45 46 46 <p> This is the simplest error diffusion method. It thresholds the image 47 to 0.5 and propagates 100% of the error the the next (right) pixel: </p> 47 to 0.5 and propagates 100% of the error the the next (right) pixel.
