Tibial torsion measurement by surface curvature.
BACKGROUND Tibial torsion is the angle between the transverse axes of the proximal and distal tibial articular surfaces. It measures the degree of twisting of the tibia around its own longitudinal axis. The accurate measurement on the magnitude of tibial torsion is of great use in monitoring derangements. It is also useful as a baseline in the event of surgical intervention. Various methods hav...

Using Near-Field Light Sources to Separate Illumination from BRDF
Simultaneous estimation of lighting and BRDF from multi-view images is an interesting problem in computer vision. It allows for exciting applications, such as flexible relighting in post-production, without recapturing the scene. Unfortunately, the estimation problem is made difficult because lighting and BRDF have closely entangled effects in the input images. This paper presents an algorithm ...
متن کاملImage-Based BRDF Measurement
We present a new image-based process for measuring surface reflectance rapidly, completely, and accurately. Requiring only a digital camera, a light source, and a convex curved test sample, our method can measure the BRDF with high resolution and accuracy over a very large domain of illumination and reflection directions. We have verified our measurements both by tests of internal consistency a...
