                         visual representations has been allowed by a novel approach to 
                         digital orientation and curvature estimation. The reported 
                         approach is strongly supported on solid concepts from differential 
                         geometry and can be effectively implemented by using the Fourier 
                         transform and its inverse. The developed framework allows not only 
                         multiple important representations of the image contours to be 
                         obtained, but also effectively supports multiscale operation, that 
                         is allowed through selective low-pass Gaussian filtering. The 
                         overall computational effort is proportional to O (N.Log (N)). 
                         Experimental examples are included that substantiate the potential 
                         of the described approach respectively to a real image.",
