Multiscale Shape and Detail Enhancement from Multi-light Image Collections
image enhancement NPR relighting shape depiction bilateral filter multiscale image processing
2016/5/24
We present a new image-based technique for enhancing the shape
and surface details of an object. The input to our system is a small
set of photographs taken from a fixed viewpoint, but under varying...
Equalization of modal dispersion in multimode fiber using spatial light modulators
Intersymbol interference the modal dispersion multimode optical fiber communication system
2015/8/11
Intersymbol interference (ISI) due to modal dispersion is the dominant limitation to the bit rate-distance product in multimode fiber-optic communication systems. If the light launched into the fiber ...

The collection and updating of 3D data is the one of the important steps for GIS applications which require fast and efficient data collection methods. The photogrammetry has been used for many years ...
Face Detection under Variable Lighting Based on Nine Point of Light
Face Detection Variable Lighting
2010/12/14
Different environment illumination has a great impact on face detection. In this paper, we present a
solution based on face relighting technology. The basic idea is that there exist nine harmonic ima...
