Dendrite Modeling (download 475 KB)

Modeling dendrites, including trees, lightning, river systems, and all manner of branching structures, has been frequently undertaken in computer graphics. We propose a new dendritic modeling framework using path planning as the basic operation.

Improved Image Quilting (download 1.3 MB)

Path planning is a great optimization technique, but the usual cost metric (sum of all path edges) is not always the best. Here, we propose applying a non-scalar path cost metric to Image Quilting, and show how we can get perceptually better results with about the same computational expense.
