Steerable Filtering Using Novel Circular Harmonic Functions with Application to Edge Detection
In this paper, we perform approximate steering of the elongated 2D Hermite-Gauss functions with respect to rotations and provide a compact analytical expressions for the related ba...

Estimation of Epipolar Geometry from Apparent Contours: Affine and Circular Motion Cases
This paper addresses the problem of estimating the epipolar geometry from apparent contours in two special cases: under weak perspective and for circular motion. An appropriate pa...

Sorting by Length-Weighted Reversals: Dealing with Signs and Circularity
Abstract. We consider the problem of sorting linear and circular permutations and 0/1 sequences by reversals in a length-sensitive cost model. We extend the results on sorting by l...

Properties of symmetric fitness functions
The properties of symmetric fitness functions are investigated. We show that a well-known encoding scheme inducing symmetric functions has the non-synonymous property and the sear...

Inversion of Circular Averages using the Funk Transform
In radar, when the wavelength of the transmitted electromagnetic wave is considerably larger than the dimension of the antenna, the received signal is modeled as the integral of t...
