Why the visual recognition system might encode the effects of illumination
1998
Vision Research
Preserved Fulltext
Together these results suggest that illumination effects such as shadow edges: (1) affect visual memory; (2) serve the function of making unambigous the three-dimensional shape; and (3) are modeled with ...
respect to object shape, rather than simply encoded in terms of their effects in the image. ...

We replace these priors with measurements from a time-of-flight (ToF) camera, and introduce a neural representation based on an image formation model for continuous-wave ToF cameras. ...
Instead of working with processed depth maps, we model the raw ToF sensor measurements to improve reconstruction quality and avoid issues with low reflectance regions, multi-path interference, and a sensor's ...
For a point light source at x (i.e., collocated with the
camera), each scene point is only lit from one direction. ...

The less general but widespread case of tracking from a static camera is also considered and a novel change detection algorithm robust to sudden illumination changes is proposed. ...
Finally, the problem of automatic tracker initialization is considered. In particular, a novel solution for categorization of 3D data is presented. ...
The main idea behind adaptive filtering schemes is that the basic source of uncertainty is due to the unknown noise covariances, and the proposed solution is to estimate them on-line from observed data ...
