Hand-crafted illustrations are often more effective than photographs
for conveying the shape and important features of an object, but
they require expertise and time to produce. We describe an image...
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...
