    Research output: Contribution to journalArticlepeer-review


    We present a new method for halftoning images by scanning the pixels in a random order and diffusing the errors by using a coefficient-reversed bilateral filter. The random traversal of pixels avoids creating artificial dot patterns that usually appear in conventional halftone images by raster scanning the pixels. The coefficient-reversed bilateral filter is effective at enhancing the edges. We apply this halftoning method to the non-photorealistic rendering of stippling images.
