Paper Abstract

We showed that advanced distortion-invariant filters such as OTSDF and DCCF filters can be used in conjunction with circular filters to obtain rotation-invariant correlation filters. The combination allows the calculation of OTSDF and DCCF filters to be greatly simplified when compared to using rotated views of an object to create a filter. The performance of the filters were different yet overall comparable indicating that perhaps different training data could have altered the results. In addition, the filters generated were real-valued so they may be implemented on a wider variety of SLMs usually associated with general distortion-invariant filters.
