“…The trajectory estimation stage provides a sequence of footprint locations, their sizes, and their orientations. The in-between footprints are generated using B-Spline interpolation [10] The idea is that we assign the brush agent to draw a painting according to a map of desired strokes which we call GL as illustrated in Figure 2. In our work, we extract this map (GL) automatically using a improved clustering approach discussed in the next section.…”

In computer graphics field, stroke-based painterly rendering (SBPR) is the program to convert photographs into paintings, such as oil painting, watercolor and sketches. Beyond specific techniques to render real photographs, major challenge is how to understand real photographs as human visual perception and cognition according to artists' painting motivation, which parts should be drawn and how to draw strokes. Before starting to draw with pigments, real artists commonly draw a sketch using simple lines to mark out final stroke layouts which navigate to control stroke drawing trajectories and poses. This can be treated as a blue print in their mind. In SBPR, it is also a powerful tool to guide strokes configuration. In this paper, we propose a image-based method to extract this blue print called guidelines (GL). We generate GL by combining color gradient and morphological structure of real photographs. In the experiment, we apply our GL into Bangladeshi traditional mask automatic animation generation with webcam video. The results show that our method is sufficient and efficient to assist SBPR generation.

Animation created using computer graphics is seen through a viewport which is dictated by what the director or producer wants the consumer to watch. This includes the usual cinematography to bring out the best dramatical effects. Consumers, however, do not have a choice but to passively receive the imagery that unfolds through the screen. This paper proposes the concept of a consumer editable animation, which aims to provide consumers with the flexibility to change attributes of the scene and also to decide what and how they want to view the final animation. Another key point is that all data are vector-based and the animation sequences are therefore rescalable.

“…To create animations, two keyframes of a set of DBSCs are given and inbetweens are automatically generated by interpolating corresponding DBSCs. In previous method 2,3 , linear interpolation is applied to points evenly taken in parametric domain of two DBSCs. No properties of the drawing, for example shapes or motion of the character, are considered, which may result in distortion and unrealistic motion in animation.…”

Disk B-spline curve (DBSC) is previously proposed for drawing and animation. To generate inbetweens, linear interpolation is applied between points evenly taken in parametric domain of two DBSCs without incorporating characteristics of shape or motion, which results in distortion and unrealistic motion in animation. In this paper, more information in keyframes is extracted and utilized in inbetween generation. Points with high curvature are computed and corresponded between strokes in interpolation, which preserves features of strokes in animation. In addition, global motion of a character or its various components is estimated and interpolated as well, which retains the shapes during the motion. By applying the information to interpolation, the distortion is eliminated and smoother sequence of animation is achieved.
