Accurate orientation for airborne mapping systems

Jan Skaloud

Stringent requirements on the accuracy of attitude determi- nation are currently a major challenge for strapdown INS/GPS integration, which is at the core of self-contained airborne remote sensing and mapping systems. This paper reviews the error models fo ...

Spline Kernels for Continuous-Space Image Processing

Michaël Unser, Thierry Blu

We present an explicit formula for spline kernels; these are defined as the convolution of several B-splines of variable widths h and degrees n. The spline kernels are useful for continuous signal processing algorithms that involve B-spline inner-products ...

Oversampled Filter Banks

Martin Vetterli

Perfect reconstruction oversampled filter banks are equivalent to a particular class of frames in t(2)(Z), These frames are the subject of this paper. First, necessary and sufficient conditions on a filter bank for implementing a frame or a tight frame exp ...

Generalized Sampling: Stability and Performance Analysis

Michaël Unser

Generalized sampling provides a general mechanism for recovering an unknown input function

f(x) \in H

from the samples of the responses of m linear shift-invariant systems sampled at 1 ⁄ mth the reconstruction rate. The system can be designed to perform ...

Investigation of a possible process identity between DRM and Linear Filtering

Sacha Krstulovic

The classical analogy between linear filtering and acoustical filtering by tubes is applied in the non-classical case where the tubes are made of unequal-length sections (such as the DRM case). It is shown that the filtering process identity is substantial ...

Displacement Structure: Theory and Applications

Ali H. Sayed

In this survey paper, we describe how strands of work that are important in two different fields, matrix theory and complex function theory, have come together in some work on fast computational algorithms for matrices with what we call displacement struct ...

Wavelets and recursive filter banks

Martin Vetterli

It is shown that infinite impulse response (IIR) filters lead to more general wavelets of infinite support than finite impulse response (FIR) filters. A complete constructive method that yields all orthogonal two channel filter banks, where the filters hav ...

FCO sampling of digital video using perfect reconstruction filter banks

Martin Vetterli

Three-dimensional nonseparable perfect reconstruction filter banks using three-dimensional nonseparable sampling by two, FCO, are proposed. Filter structures are derived and applied to digital video. Separation into two bands is obtained, and it is shown t ...

Theory of two-dimensional multirate filter banks

Martin Vetterli

Results are presented on 2-D FIR (two-dimensional finite-impulse-response) filter banks for multirate applications. The theory is valid for all sampling lattices; conditions for alias-free and perfect signal reconstruction are derived. Synthesis structures ...

Running FIR and IIR filtering using filter banks

Martin Vetterli

The computational complexity of running FIR (finite-impulse response) and IIR (infinite-impulse response) filtering using multirate filter banks is considered. No restrictions are put on signal, filter, or block lengths. It is shown how to map long running ...
