Multiview 3D Tracking with an Incrementally Constructed 3D Model
We propose a multiview tracking method for rigid objects. Assuming that a part of the object is visible in at least two cameras, a partial 3D model is reconstructed in terms of a ...

Detecting Photographic Composites of People
The compositing of two or more people into a single image is a common form of manipulation. We describe how such composites can be detected by estimating a camera’s intrinsic par...

Concentric Mosaic(s)Planar Motion and 1D Cameras
General SFM methods give poor results for images captured by constrained motions such as planar motion of concentric mosaics (CM). In this paper, we propose new SFM algorithms for...

Transforming Camera Geometry to A Virtual Downward-Looking Camera: Robust Ego-Motion Estimation and Ground-Layer Detection
This paper presents a robust method to solve the two coupled problems: ground layer detection and vehicle egomotion estimation, which appear in visual navigation. We virtually rot...
