Creating Watercolor Style Images Taking Into Account Painting Techniques

Abstract

Research for creating impressive images like paintings has attained more and more importance because of the recent growth in processing images. Among many painting styles, watercolor style gives a strong impression because of its thin colors and its soft appearance. This paper proposes a method to create watercolor style images from input images, for instance photographs. In contrast with the previously proposed watercolor methods that focuses only on simulating the effects of watercolor medium such as the mottled appearance and the color glazing, the proposed method also considers how the watercolor paintings are painted in order to simulate artists' painting techniques. In the proposed method, artists' painting techniques are represented using painting rules. Several painting rules are provided, in addition, user can specify their own painting rules. These painting rules are used for generating strokes to paint the objects. Painting techniques are simulated by first detecting the objects in the input image and generating strokes for each object according to the painting rules. The properties of watercolor medium are simulated by approximating each stroke with sampling points and diffuses their color to nearby pixels. Using the proposed method, a user can interactively create watercolor style images.

Edge- and substrate-based effects for watercolor stylization

“…To replicate (usually a subset of) those effects, a large variety of approaches have been proposed, going from simple image filters [Bousseau et al 2006;Johan et al 2004] to physical simulations [Curtis et al 1997;Small 1991]. In this paper we focus on the interactive stylization of 3D animations, for which an artist cannot draw each image manually neither with traditional techniques nor using physical [Chu and Tai 2005;Van Laerhoven and Van Reeth 2005;You et al 2013] or procedural Lu et al 2013] simulations.…”

Video watercolorization using bidirectional texture advection

“…A significant body of research has been devoted to creating watercolor rendering for static images [Small 1991;Curtis et al 1997;Lum and Ma 2001;Lei and Chang 2004;Van Laerhoven et al 2004;Johan et al 2005;Luft and Deussen 2006;Bousseau et al 2006]. Commercial tools, like Photoshop TM and The GIMP, also provide ways of creating watercolor-like renderings from images.…”

“…Mao et al [4] have proposed a method to generate a pencil drawing-style by using a vector field in the image and white noise, and Johan [5] has proposed a method to create watercolor-style images taking into account paint-ing techniques.…”
