Enhanced error diffusion by using peak position profiles |
摘要 |
A method for enhanced error diffusion. The method includes the steps of selecting values for a first level of peak positions, placing these peak positions in selected positions of a matrix, creating a peak position profile. The peak position profiles are then used to adjust the error threshold by applying the peak position profile. The profiled error threshold is then used to calculate error for the current input pixel value and the resulting error is diffused to the neighbors of the current pixel.
