A Natural Image Pointillism with Controlled Ellipse Dots

A Natural Image Pointillism with Controlled Ellipse Dots

This paper presents an image-based artistic rendering algorithm for the automatic Pointillism style. At first, ellipse dot locations are randomly generated based on a source image; then dot orientations are precalculated with help of a direction map; a saliency map of the source image decides long a...
