چکیده

The rst processing step in computational early vision usually consists of convolutions with a number of kernels. These kernels often are derived from a mother kernel that is rotated, scaled, or deformed with respect to other degrees of freedom. This paper presents an eecient computational approach to calculate the responses of arbitrary mother kernels with arbitrary deformations. Analytical solutions to this problem in most cases are diicult or not possible. Therefore, we present in this paper a numerical approach that emphasizes an algebraical point of view. 1. INTRODUCTION It seems to be a natural demand on the early vision part of a general vision system to provide explicit information of images about orientation, scale, and other degrees of freedom. Since a few years there has been a growing interest in generating continuous responses of lters with respect to these degrees of freedom. Instead of resulting in a tremendous computational burden the application of the steerable

X-Y separable pyramid steerable scalable kernels

A new method for generating x-y separable steerable scalable approximations offilter kemels is proposed which is based on a generalization of the Singular Value Decomposition (SVD) to 3 dimensions. This “pseudo-SVD ” impmves upon a p w w u s scheme due to Pemna in that it reduces convolution time and storage requirements. An adaptation of the pseudo-SVD is proposed to generate steerable and sca...

Learning Steerable Filters for Rotation Equivariant CNNs

In many machine learning tasks it is desirable that a model’s prediction transforms in an equivariant way under transformations of its input. Convolutional neural networks (CNNs) implement translational equivariance by construction; for other transformations, however, they are compelled to learn the proper mapping. In this work, we develop Steerable Filter CNNs (SFCNNs) which achieve joint equi...

An unified theory for steerable and quadrature filters

In this paper, a complete theory of steerable filters is presented which shows that quadrature filters are only a special case of steerable filters. Although there has been a large number of approaches dealing with the theory of steerable filters, none of these gives a complete theory with respect to the transformation groups which deform the filter kernel. Michaelis and Sommer (Michaelis and S...

An Efficient Method for Tensor Voting Using Steerable Filters

In many image analysis applications there is a need to extract curves in noisy images. To achieve a more robust extraction, one can exploit correlations of oriented features over a spatial context in the image. Tensor voting is an existing technique to extract features in this way. In this paper, we present a new computational scheme for tensor voting on a dense field of rank-2 tensors. Using s...
