There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract
A seamless blending of the real and virtual worlds is key to increased immersion and improved user experiences for augmented reality (AR). Photorealistic and non-photorealistic rendering (NPR) are two ways to achieve this goal. Non-photorealistic rendering creates an abstract version of both the real and virtual world by stylization to make them indistinguishable. This could be particularly useful in some applications, e.g., AR/VR aided machine repair, or for certain AR games with artistic stylization. Temporal coherence is a key problem for all NPR algorithms. Rendered results are temporal coherent when each frame smoothly and seamlessly transitions to the next one without visual flickering and artifacts that distract the eye from smoothness. In this thesis we present three NPR algorithms with coherence for AR, two that are image space algorithms and one that is a mode space algorithm. We utilize the information from both the real content and virtual content to maintain coherence in our algorithms.
