Perceptually-driven decision theory for interactive realistic rendering
2003
ACM Transactions on Graphics
Preserved Fulltext
The approach uses efficient perceptual metrics within a decision theoretic framework to optimally order rendering operations, producing images of the highest visual quality within system constraints. ...
We demonstrate the usefulness of this approach for various applications such as diffuse texture caching, environment map prioritization and radiosity mesh simplification. ...
Thanks to Peggy Andersen for proofreading the paper multiple times and Jeremy Selan for technical help. Special thanks to Don Greenberg for his unconditional support during tough times. ...

We will not speak about importance-driven radiosity solutions, as those methods are based on using geometric visibility rather than on using human perception-aware techniques. ...
In the second part of the report we concentrate on known radiosity methods that already use these perceptual approaches to predict different visible errors of the result of the radiosity computation. ...
His main research topic is perceptual approaches to radiosity solutions. ...
