Painterly rendering with focusing effect

Abstract

In this paper, we present an algorithm that provides a focusing effect by transforming the character of strokes. The focusing point can be obtained by the density of edges, which refers to the amount of edges in a specific area. After the determination of the focusing point, the following work should be done. First, details and abstraction should be expressed by adjusting the brush size centering on the focusing point. Second, the direction of the brush should be determined so the view is focused through interpolation using the focusing point. Third the focusing point should be exaggerated by adjusting the blur and highlight effects. The focusing effects generated on the desired part through the above procedure can provide an effect of oil painting that has been realized by a human being. © 2012 Springer Science+Business Media.
