“…NPR techniques create more impressive images than the photorealistic rendering does, thus a promising technique to be used in the computer games, movies, and other entertainment fields which tend to place emphasis on the visual impact. A number of NPR methods have been proposed including silhouette-based methods [5,14], pen-and-ink methods [8,20], colored pencil drawing [21], wax crayons [19], stylized rendering [2,4,7], mosaics creation [6,9], and so on.…”

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.

“…We use the rule that pixels on the same 2D brush path with the same stroke path ID from the previous frame should be grouped as a stroke path, and parameterized as one stroke, in a similar way to the key idea of Ref. [6].…”

Stylized strokes for coherent line drawings

Temporal coherence is one of the central challenges for rendering a stylized line. It is especially difficult for stylized contours of coarse meshes or nonuniformly sampled models, because those contours are polygonal feature edges on the models with no continuous correspondences between frames. We describe a novel and simple technique for constructing a 2D brush path along a 3D contour. We also introduce a 3D parameter propagation and re-parameterization procedure to construct stroke paths along the 2D brush path to draw coherently stylized feature lines with a wide range of styles. Our method runs in real-time for coarse or non-uniformly sampled models, making it suitable for interactive applications needing temporal coherence.

“…Its implementation on 3D geometry include stylization or abstraction and various techniques are used (Bousseau et al, 2007;Kalinins et al, 2009, Kang, Lee & Chui, 2009Kyprianidis, Kang & Döllner, 2009). The NPR studies are in focus especially in 2D and 3D graphic.…”

The aim of the research was to study the issue of drawing 2D objects and environments in perspective and attempted to ease the process of drawing them with the aid of three-dimensional computer graphics. The goal of the research was to develop the method, which would exclude the need to trace three-dimensional models, which many digital artists use as a guide when making drawings. The need to trace has been eliminated by finding a procedure to render three-dimensional models to appear drawn – to appear drawn by an artist who has a stylized line style. After researching various techniques of rendering, Sketchup was used to make and apply a Sketchup style which emulated a line style. After that, various tests were performed using computer measurements and questionnaires to determine if the observers could distinguish between three-dimen-sional renders and two-dimensional drawings. The results have shown that very few participants notice three-dimensional graphics rendered with Sketchup. Even among the few observers who did notice the presence of three-dimensional models, none detected even half. The results confirmed the adequateness of the methodology, which enables a more correct creation of element in perspective and convinces the observers that the entire image is stylistically uniform hand drawn image
