Detecting Highly Oscillatory Signals by Chirplet Path Pursuit
Signal Detection Nonparametric Testing Likelihood Ratios Adaptivity Chirps Chirplets Time-Frequency Analysis Gravitational Waves Graphs Shortest Path in a Graph Dynamic Programming
2015/6/17
This paper considers the problem of detecting nonstationary phenomena, and chirps in particular, from very noisy data. Chirps are waveforms of the very general form A(t) exp(iλ ϕ(t)), where λ is ...

Detecting Social Networks Using (α, β)-Communities
2012/12/3
An (α, β)-community is a subset of vertices C with each vertex in C connected to at least β vertices of C (self-loops counted) and each vertex outside of C connected to at most α vertices of C (α < β)...

In many social networks, there exist two types of users that exhibit different influence and different behavior. For instance, statistics have shown that less than 1% of the Twitter users (e.g. entert...
DCT-Based Videoprinting on Saliency-Consistent Regions for Detecting Video Copies with Text Insertion
DCT-Based Videoprinting Saliency-Consistent Regions Detecting Video Copies
2010/12/20
Ideal video fingerprinting should be robust to various practical distortions.Conventional fingerprinting mainly copes with natural distortions (brightness change, resolution reduction, etc.), while al...
Detecting Violent Scenes in Movies by Auditory and Visual Cues, Pacific-Rim Conference on Multimedia
Movies Auditory Visual Cues
2010/12/17
Abstract. To detect violence in movies, we present a three-stage method integrating visual and auditory cues. In our method, those shots with potential violent content are first identified according t...
