Approximation properties relative to continuous scale space for hybrid discretisations of Gaussian derivative operators

Approximation properties relative to continuous scale space for hybrid discretisations of Gaussian derivative operators

This paper presents an analysis of properties of two hybrid discretisation methods for Gaussian derivatives, based on convolutions with either the normalised sampled Gaussian kernel or the integrated Gaussian kernel followed by central differences. The motivation for studying these discretisation me...
