Registration Of Sheared Images Using Phase Correlation
MetadataShow full item record
Phase Correlation is a well-known method for registration of images that are related by similarity transforms. Its extension to registration of affine transformed images is not straightforward. This paper presents a method for recovering the transformation parameters of images that have been translated, shifted, rotated and arbitrarily sheared. It is effective for recovering shearing parameters with magnitudes of up to 40% of the image size. The proposed method makes use of Phase Correlation in conjunction a Hough based technique. Theory, methodology and experimental results are presented.
