This paper presents two methods, based on the rational approximation of functions, for designing Gabor like IIR filters with reduced computational complexity. The performance of the designed filters is discussed and comparisons with other approaches are ma ...
By interpreting the Green-function reproduction property of exponential splines in signal processing terms, we uncover a fundamental relation that connects the impulse responses of allpole analog filters to their discrete counterparts. The link is that the ...
Mol. dynamics simulations at 298 K are used to study an aq. dissolved dye (eosin Y) adsorbed at the TiO2(1 1 0) surface to ext. static and dynamic information of solvation. Differences in the phys. behavior of the dye at the surface and in bulk H2O are com ...
The system and method for estimating impulse response of a wideband communication channel represented as linear combination of L time-shifted pulsed P1 (t) with propagation coefficients a1, comprising functionalities or steps for obtaining an ultrawideband ...
The CSE; has developed an optomechanical linear scanner. This scanner has a limited displacement range, performed with high resolution. The resolution is obtained through a very high precision motion guiding of the scanner itself. This paper describes the ...
We present a new scheme for digital watermarking of point-sampled geometry based on spectral analysis. By extending existing algorithms designed for polygonal data to unstructured point clouds, our method is particularly suited for scanned models, where th ...
We present a procedure for designing interpolation kernels that are adapted to time signals; i.e., they are causal, even though they do not have a finite support. The considered kernels are obtained by digital IIR filtering of a finite support function tha ...
Different approaches to the moving object detection in multi-object tracking systems use dynamic-based models. In this paper we propose the use of a discrete choice model (DCM) of pedestrian behavior and its application to the problem of the target detecti ...
CDMA and MIMO-CDMA systems using RAKE receivers are heavily limited by self- and multiple-access-interference. Linear equalization is a means to remove this interference, however it is often not practical due to the enormous complexity, especially in the M ...

We present a simple but generalized interpolation method for digital images that uses multiwavelet-like basis functions. Most of interpolation methods uses only one symmetric basis function; for example, standard and shifted piecewise-linear interpolations ...
