| Title: |
Performance Relighting and Reflectance Transformation With Time-Multiplexed Illumination |
| Abstract: |
A lighting apparatus may be configured to illuminate a subject while the
subject is undergoing a motion during a time period. An imaging system
may be configured to generate image data representative of a sequence of
frames of the moving subject. A controller may be configured to drive the
lighting apparatus and the imaging system so that the lighting apparatus
sequentially illuminates the moving subject with a time-multiplexed
series of lighting conditions, and so that each one of the frames shows
the subject illuminated with a respective one of the lighting conditions.
The controller may be further configured to process the image data to
generate re-illumination data representative of novel illumination
conditions under which the subject can be re-illuminated, subsequent to
the time period.
