"Detection of Outer Rotations on 3D-Vector Fields with Iterative 
Geometric Correlation"


zum Inhalt:

Correlation is a common technique for the detection of shifts. Its 
generalization to the multidimensional geometric correlation in Clifford 
algebras has proven a useful tool for color image processing, because it 
additionally contains information about rotational misalignment. In this 
paper we prove that applying the geometric correlation iteratively can 
detect the outer rotational misalignment for arbitrary three-dimensional 
vector fields. Thus, it develops a foundation applicable for image 
registration and pattern matching. Based on the theoretical work we have 
developed a new algorithm and tested it on some principle examples.

"Detection of Total Rotations on 2D-Vector Fields with Geometric 
Correlation"


zum Inhalt:

Correlation is a common technique for the detection of shifts. Its 
generalization to the multidimensional geometric correlation in Clifford 
algebras additionally contains information with respect to rotational 
misalignment. It has been proven a useful tool for the registration of 
vector fields that differ by an outer rotation. In this paper we proof 
that applying the geometric correlation iteratively has the potential to 
detect the total rotational misalignment for linear two-dimensional 
vector fields. We further analyze its effect on general analytic vector 
fields and show how the rotation can be calculated from their power 
series expansions.

Alle Interessierten sind im Namen von Prof. Dr. Scheuermann herzlich 
eingeladen.
