"Seeing the World as It Really is
: Connection of Photometric Distortions from Digital Cameras"
Radiance Analysis
- shape from shading
- 3D stereo reconstruction
- face detection
<Problems>
1. Limit of Depth of Fields
2. Lens Aberration
3. Vignetting
4. Sensor Dust (eg. CCD)
5. Image Blur "Time-spanning"
6. Demosaicking
7. White Balance
3-1. optical
off-axis illumination
"cos^4 law"
3-2. geometric
aperture effect
* Levenberg-Marquardt algorithm
5.
Blur due to arbitrary motion
Auxiliary Sensor
