Unified theory for joint covariance properties under geometric image transformations for spatio-temporal receptive fields according to the generalized Gaussian derivative model for visual receptive fields
Tony Lindeberg
The influence of natural image transformations on receptive field responses is crucial for modelling visual operations in computer vision and biological vision. In this regard, cov…
Approximation properties relative to continuous scale space for hybrid discretizations of Gaussian derivative operators
Tony Lindeberg
This paper presents an analysis of properties of two hybrid discretization methods for Gaussian derivatives, based on convolutions with either the normalized sampled Gaussian kerne…
A time-causal and time-recursive analogue of the Gabor transform
Tony Lindeberg
This paper presents a time-causal analogue of the Gabor filter, as well as a both time-causal and time-recursive analogue of the Gabor transform, where the proposed time-causal rep…
Orientation selectivity properties for the affine Gaussian derivative and the affine Gabor models for visual receptive fields
Tony Lindeberg
This paper presents a theoretical analysis of the orientation selectivity of simple and complex cells that can be well modelled by the generalized Gaussian derivative model for vis…
