MIRO: Progress Report
First Year Report
This first year was successful in term of creating links between the two teams, new results and projects, and submissions. The main results are the following:
- Simplification and Extration of feature lines: We have developed some news approaches for the simplification and the extraction of features lines. The simplification is based on a perceptual metrics in order to keep only the most legible lines. For the extraction, we have defined a user study that will allow to classify what are the most important geometric criteria for the line extraction.
- New NPR styles: We have developed two new rendering styles. The first one is a watercolor style. Compared to previous solutions, this approach is coherent over time. It can be used for computed animations. The second is an extension of the "toon" style. This extension allows a large variety of new styles, like the atmospheric effect.
Based on these works, we have 1 publication and 3 submissions.
