Optimal radial contour tracking by dynamic programming
A common problem in most active contour methods is that the recursive searching scheme can only return a local optimal solution. Furthermore, the internal energy of the snake is n...

Image-based rendering for mixed reality
In this paper, we propose an image-based approach to synthesize a novel view image for mixed reality (MR) systems. Theoretically, the image- based method is good for synthesizing ...

High-quality isosurface rendering with exact gradient
We address the task of rendering by ray tracing the isosurface of a high-quality continuous spline model of volumetric discrete and regular data. By expressing the spline model as...
