Efficient search of music pitch contours using wavelet transforms and segmented dynamic time warping
We propose a method of music melody matching based on their “continuous” (or “time-frame-based”) pitch contours. Most previous methods using frame-based contours either ma...

Processing relaxed skylines in PDMS using distributed data summaries
Peer Data Management Systems (PDMS) are a natural extension of heterogeneous database systems. One of the main tasks in such systems is efficient query processing. Insisting on co...

Streaming Surface Reconstruction Using Wavelets
We present a streaming method for reconstructing surfaces from large data sets generated by a laser range scanner using wavelets. Wavelets provide a localized, multiresolution rep...

Detecting Network Anomalies Using Different Wavelet Basis Functions
Signal processing techniques have been applied recently for analyzing and detecting network anomalies due to their potential to find novel or unknown intrusions. In this paper, we...

Change Detection in Time Series Data Using Wavelet Footprints
In this paper, we propose a novel approach to address the problem of change detection in time series data. Our approach is based on wavelet footprints proposed originally by the si...
