The Trace transform and its applications
The trace transform, a generalisation of the Radon transform, consists of tracing an image with straight lines along which certain functionals of the image function are calculated. Different functionals that can be used may be invariant to different transformations of the image. The paper presents the properties the functionals used must have for the constructed features to be invariant to rotation, translation and scaling, and for the recovery of the transformation parameters.
