Elliptical Gaussian filters
نویسندگان
چکیده
A multiscale region detector for low-level image analysis is described. The basis of the detector is a set offilters similar to the Laplacian of an elliptical Gaussian. The responses of these Flters to ideal ellipses are derived, and equations for determining the parameters of detected ellipses from the filter responses are found. The use of scale-space techniques to eliminate false ellipse sites in real images is described.

متن کاملDevelopment of Nonlinear Lattice-Hammerstein Filters for Gaussian Signals
In this paper, the nonlinear lattice-Hammerstein filter and its properties are derived. It is shown that the error signals are orthogonal to the input signal and also backward errors of different stages are orthogonal to each other. Numerical results confirm all the theoretical properties of the lattice-Hammerstein structure.
متن کاملBasic elliptical Gaussian wave and beam in a uniaxial crystal.
Electromagnetic beams in a uniaxial crystal are treated with emphasis on the extraordinary mode. A virtual source that generates a basic elliptical Gaussian wave propagating obliquely to the optic axis is identified. An exact expression is obtained for this basic elliptical Gaussian wave that simplifies to the corresponding basic elliptical Gaussian beam in the appropriate limit. In the directi...
متن کاملPoster:Continuous FVR of Irregularly Sampled Data Using Gaussian RBFs
We describe a Fourier Volume Rendering (FVR) algorithm for datasets that are irregularly sampled and require anisotropic (e.g., elliptical) kernels for reconstruction. We sample the continuous frequency spectrum of such datasets by computing the continuous Fourier transform of the spatial interpolation kernel which is a radially symmetric Gaussian basis function (RBF) that may be anisotropicall...
