This paper presents a novel hybrid technique for robust detection of rings in phase correlation surfaces. Phase correlation of affine transformed images has been shown to result in rings on the correlation surface. The reliability of the classical approach to ring detection via the Hough Circle Transform is sensitive to correlation noise. Alternative methods that are more resilient are very computationally intensive. A hybrid method that preserves the relative efficiency of the HCT that is robust in the presence of correlation noise is proposed.This paper presents a novel hybrid technique for robust detection of rings in phase correlation surfaces.
