Water painting is an art, where the result and experience strongly depend on the process of creating it. Color is injected by the artist in a controlled way and diffuses into a final state. ...
The geodesic distance builds the mathematical foundation for our animated diffusion. We add a time-dependent weight function to generate a diffusion-like spreading effect. ...

We also applied our geodesic cut scheme to a number of image editing tasks as demonstrated in additional experiments. ...
Other than using various pixel-level contrast definitions, we exploited global image structures and proposed a new geodesic method dedicated for salient object detection. ...
There are many leaps between sections and paragraphs and unexplained statements, making the paper hard to understand and evaluate the correctness of the proposed methods. ...
