Title:
Increased Accuracy Orientation Estimation from Omnidirectional Images using the Spherical Fourier Transform 
Abstract:
Orientation estimation based on image data is a key technique in many applications and robust estimates are possible in case of omnidirectional images. A very efficient technique is to solve the problem in Fourier space. In this paper we present a fast and simple method to overcome one of the main drawbacks of this approach, namely the large quantization steps. Due to high memory demands, the Fourier-based solution can be computed on low-resolution input only and the resulting rotation estimate...    »
