Spatio-Frequency Analysis of Scale-Space Filtering
نویسنده
چکیده
We study implementation issues for spatial convolution lters and their Fourier alternative, with the aim to optimise the accuracy of lter output. We focus on Gaussian scale-space lters and show that there exists a trade-o scale that subdivides the available scale range in the sense that the smaller and larger scales are best extracted by Fourier, respectively spatial ltering.

Application of Single-Frequency Time-Space Filtering Technique for Seismic Ground Roll and Random Noise Attenuation
Time-frequency filtering is an acceptable technique for attenuating noise in 2-D (time-space) and 3-D (time-space-space) reflection seismic data. The common approach for this purpose is transforming each seismic signal from 1-D time domain to a 2-D time-frequency domain and then denoising the signal by a designed filter and finally transforming back the filtered signal to original time domain. ...
متن کاملA Spatio-Frequency Trade-Off Scale for Scale-Space Filtering
ÐWe study implementation issues for spatial convolution filters and their Fourier alternative, with the aim to optimize the accuracy of filter output. We focus on Gaussian scale-space filters and show that there exists a trade-off scale that subdivides the available scale range into two subintervals of equal length. Below this trade-off scale Fourier filtering yields more accurate results than ...
متن کاملMethods of Data Analysis Correlation functions, spectral estimation, filtering
Characterizing spatio-temporal properties of a signal. In the analysis of experimental signals, either scalar time series or spatio-temporal processes, oneand two-point statistics provide the basic description of the system that is usually sufficiently amenable to reliable estimation from data. Often (but as we will see shortly, not always), physically interesting phenomena – including collecti...
متن کاملA New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...
متن کاملDesign of Linear Cellular Neural Networks for Motion Sensitive Filtering
Recently, several researchers have proposed using spatio-temporal filters for image motion analysis. For example, the optical flow field can be calculated from the output of a set of spatio-temporal filters. Some of the most popular spatio-temporal filters are the space-time Gabor filters, obtained by convolving a time varying image with a space-time Gabor function. Based on the cellular neural...
