A theory of multi-layer flat refractive geometry
Flat refractive geometry corresponds to a perspective camera looking through single/multiple parallel flat refractive mediums. We show that the underlying geometry of rays corres...

Illuminating micro geometry based on precomputed visibility
Many researchers have been arguing that geometry, bump maps, and BRDFs present a hierarchy of detail that should be exploited for efficient rendering purposes. In practice howeve...

Simultaneous linear estimation of multiple view geometry and lens distortion
A bugbear of uncalibrated stereo reconstruction is that cameras which deviate from the pinhole model have to be pre-calibrated in order to correct for nonlinear lens distortion. I...

Supportedness and tameness differentialless geometry of plane curves
—We introduce a class of planar arcs and curves, called tame arcs, which is general enough to describe (parts of) the boundaries of planar real objects. A tame arc can have smoot...

Non-Rigid Image Transformation for Assessing Changes in Fluorescence Imaging Data of Molecular Activity in Time-Dependent Geomet
This paper presents an image processing framework for assessing molecular activity changes from fluorescent data in time-dependent geometries. The aim of our work is to provide th...
