Image processing and computer vision have robust methods for feature extraction and the computation of derivatives of scalar fields. Furthermore, interpolation and the effects of applying a filter can be analyzed in detail and can be advantages when applying these methods to vector fields to obtain a solid theoretical basis for feature extraction.

The goal of this paper is to transfer image processing to vector fields and flow visualization by defining a suitable convolution operation. For this, a multiplication of vectors is necessary. Clifford algebra provides such a multiplication of vectors. So we define a Clifford convolution on vector fields with uniform grids. The Clifford con-volution works(More)
