Abstract
A method of creating watercolor images from a source image may include some or all of: scaling down and lightening the source image; converting the lightened image to a single channel grayscale image; blending a noise pattern with the lightened image to add random jitter; overlaying an edge detection map to produce an edge buffered control image; determining a main set of colors in the source image: determining boundaries for each region where the main set of colors appear; coloring in multiple passes using one color at a time, with a diffusion of water technique emulating wet-on-wet watercoloring; coloring each of the main set of colors, by coloring from a light to dark order; enhancing the edges of the regions to model the areas where a watercolor artist would maintain separation; and compositing to add sedimentation texture; flocculation texture; a drawing layer; and a paper texture pattern.
