A Natural Image Pointillism with Controlled Ellipse Dots

Figure 3

Dot-placement strategy and rendering process: from large dots to small dots, from nonsalient areas to salient areas, one by one, layer-by-layer. (a) Source image; (b) saliency image; (c) final Pointillism with 10000 dots; (c1)~(c10) rendering process from 100 dots to 1000 dots, 2000 dots until 9000 dots, taking the saliency image as canvas image so as to check the placement strategy. In real rendering process, the blurred source image is taken as a canvas image.
