A Logic for PTIME and a Parameterized Halting Problem
In [7] Nash, Remmel, and Vianu have raised the question whether a logic L, already introduced by Gurevich in 1988, captures polynomial time, and they give a reformulation of this ...

Local minima free Parameterized Appearance Models
Parameterized Appearance Models (PAMs) (e.g. Eigentracking, Active Appearance Models, Morphable Models) are commonly used to model the appearance and shape variation of objects in...

The Parameterization of Joint Rotation with the Unit Quaternion
Abstract. Unit quaternion is an ideal parameterization for joint rotations. However, due to the complexity of the geometry of S3 group, it’s hard to specify meaningful joint cons...

Contour People: A Parameterized Model of 2D Articulated Human Shape
We define a new “contour person” model of the human body that has the expressive power of a detailed 3D model and the computational benefits of a simple 2D part-based model....

On the fixed-parameter tractability of parameterized model-checking problems
In this note, we show, through the use of examples, how generic results for proving fixed-parameter tractability which apply to restricted classes of structures can sometimes be m...
