The Assumed Light Direction for Perceiving Shape from Shading
Shape-from-shading light-from-above shape perception, Lambertian shading
2016/5/24
Recovering 3D shape from shading is an ill-posed problem that the
visual system can solve only by making use of additional information
such as the position of the light source. Previous research has...
Illumination Transfer Using Homomorphic Wavelet Filtering and Its Application to Light-Insensitive Face Recognition
Homomorphic Wavelet Filtering Light-Insensitive Face Recognition
2008/12/31
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image)to another face image (refere...
