Efficient Method for Space-Variant Low-Pass Filtering

We propose a method for efficiently performing space-variant (SV) filtering, which we apply here to the low-pass case. It is based on using a small set of N a priori fixed reference kernels, which are obtained by applying different spatial scaling factors to a mother smoothing filter. The set of 2-D signals obtained by filtering the input image with these kernels is linearly combined to achieve...

Delay Spoofing Reduction in GPS Navigation System based on Time and Transform Domain Adaptive Filtering

Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...

Frequency-dependent PSP depression contributes to low-pass temporal filtering in Eigenmannia.

This study examined the contribution of frequency-dependent short-term depression of PSP amplitude to low-pass temporal filtering in the weakly electric fish Eigenmannia. Behavioral and neurophysiological methods were used. Decelerations of the electric organ discharge frequency were measured in response to continuous and discontinuous electrosensory stimuli. Decelerations were strongest (media...

Detection of phrase boundaries in Japanese by low-pass filtering of fundamental frequency contours

Major syntactic boundaries are often accompanied by a rise in the phrase component of the fundamental frequency (F0) contour. Detecting such rises, therefore, can be signi cantly helpful to the speech recognition process. We developed a method to detect syntactic boundaries with phrasecomponent rise (henceforth, phrase boundaries), based on the compression of the accent component of the F0 cont...

Feature-Based Nonlocal Polarimetric SAR Filtering

Polarimetric synthetic aperture radar (PolSAR) images are inherently contaminated by multiplicative speckle noise, which complicates the image interpretation and image analyses. To reduce the speckle effect, several adaptive speckle filters have been developed based on the weighted average of the similarity measures commonly depending on the model or probability distribution, which are often af...
