Re-ordered error diffusion for fast implementation

摘要

A method, non-transitory computer readable medium, and apparatus for performing error diffusion are disclosed. For example, the method quantizes an error for a first pixel of a plurality of pixels in a first row, diffuses the error to an adjacent pixel of the plurality of pixels in the first row, performs the quantizing and the diffusing for each remaining pixel of the plurality of pixels in the first row and applies the error that is quantized for each one of the plurality of pixels the first row in a desired number of different directions in a plurality of parallel operations that is equal to the desired number of different directions.

1. A method for performing error diffusion, comprising:
quantizing, by a processor, an error for a first pixel of a plurality of pixels in a first row; diffusing, by the processor, the error to an adjacent pixel of the plurality of pixels in the first row; performing, by the processor, the quantizing and the diffusing for each remaining pixel of the plurality of pixels in the first row; and applying, by the processor, the error that is quantized for each one of the plurality of pixels in the first row in a desired number of different directions in a plurality of parallel operations that is equal to the desired number of different directions.
