Geometric Calibration of Third-Generation Computed Tomography Scanners from Scans of Unknown Objects using Complementary Rays
To achieve good image quality for computed tomography scans, it is important to accurately know the geometrical relationship between the x-ray source, detector, and axis of rotati...

Seeing Things: Inventive Reasoning with Geometric Analogies and Topographic Maps
This paper examines two seemingly unrelated qualitative spatial reasoning domains; geometric proportional analogies and topographic (landcover) maps. We present a Structure Matchin...

Geometric constraints on 2D action models for tracking human body
We propose a 2D model-based approach for tracking human body parts during articulated motion. A human is modeled as a stick figure with thirteen landmarks, and an action is a sequ...

A Geometrically Robust Watermarking Scheme Based on Self-Recognition Watermark Pattern
Presently, almost all of the watermarking algorithms resistant to geometric attacks are dependent on the synchronization. In this paper, a geometrically robust watermarking scheme...
