Abstract: The "gradient product transform" is a recently proposed image filter for assigning each image point a symmetry score based on scalar products of gradients. In this article, we show that the originally suggested method for finding the radius of the symmetry region is unreliable, and a more robust method is presented. Moreover, we extend the symmetry transform to rectangular symmetry regions so that it is more robust with respect to skew, and the transform is generalised to also work with three dimensional image data. We apply the transform to two different problems: detection of objects with rotational symmetry, and blood vessel extraction from medical images. In an experimental comparison with other solutions for these problems, the gradient product transform performs comparable to the best known algorithm for rotational symmetry detection, and better than the vesselness filter for blood vessel extraction.
