  author={Luis Puig and Jose de Jes{\'u}s Guerrero},
In this chapter, we present a new approach to compute the scale-space of any omnidirectional image acquired with a central projection system. When these cameras are central they are explained using the sphere camera model, which unifies in a single model, conventional, paracatadioptric, and hypercatadioptric systems. Scale space is essential in the detection and matching of interest points, in particular scale-invariant points based on Laplacian of Gaussians, like the well known SIFT. We… CONTINUE READING
