Recovering Shape and Reflectance Model of Non-Lambertian Objects from Multiple Views
This paper proposes an algorithm to simultaneously estimate both the 3D shape and parameters of a surface reflectance model from multiple views of an object made of a single mater...

Piecewise Quadratic Reconstruction of Non-Rigid Surfaces from Monocular Sequences
Abstract. In this paper we present a new method for the 3D reconstruction of highly deforming surfaces (for instance a flag waving in the wind) viewed by a single orthographic came...

Camera Pose and Calibration from 4 or 5 Known 3D Points
We describe two direct quasilinear methods for camera pose (absolute orientation) and calibration from a single image of 4 or 5 known 3D points. They generalize the 6 point `Direc...

Correction for external LOR effects in listmode reconstruction for PET
In PET imaging listmode is an alternative for projections to store the acquisition data with more accuracy. The reconstruction starting from the listmode format requires different...

Real time volumetric shadows using polygonal light volumes
This paper presents a more efficient way of computing single scattering effects in homogeneous participating media for real-time purposes than the currently popular ray-marching b...
