Wavelet-Neural Networks Based Face Recognition (zip): Wavelet-Neural Networks Based Face Recognition System - Matlab source code. Wavelet transforms are used to reduce image information redundancy because only a subset of the transform coefficients are necessary to preserve the most important facial features such as hair outline, eyes and mouth. We demonstrate experimentally that when Wavelet coefficients...; Tags: Coefficient, Matlab, Wavelet; Software downloads 2006-06-21
Neural Networks - DCT for Face Identification (zip): Neural Networks - DCT for Face Identification. Matlab source code. High information redundancy and correlation in face images result in inefficiencies when such images are used directly for recognition.

Channel Estimation for OFDM Systems in Case of Insufficient Guard Interval Length: This paper presents a novel method used to channel estimation for OFDM systems in case of insufficient guard interval length. This method suppresses additive noise and interference components by averaging the estimated channel coefficients in the time direction. The channel coefficients obtained after time averaging must be added to an...; Tags: Coefficient, OFDM, Wireless; White papers
Face Recognition Based On Overlapping DCT (zip): Face Recognition Based On Overlapping DCT - Matlab source code. In the JPEG image compression algorithm, the input image is divided into 8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each block. The DCT coefficients are then quantized, coded, and transmitted. The JPEG receiver (or JPEG file...; Tags: Algorithm, Coefficient, JPEG, Face Recognition, Image, Luigi Rosa, DCT Coefficient, Feature Vector, Engineering; Software downloads 2008-08-31

Analysis of TCP Westwood + in High Speed Networks: TCP Westwood+ is modelled and analyzed using stochastic recursive equations. It is shown that for links with Poisson losses and independent and varying delays, TCP Westwood converges to a stationary process with a finite average throughput. The resulting throughput is computed explicitly, and it is shown that it does not...; Tags: Network, TCP, Analysis, TCP Westwood+, Tcp/Ip, Networking; White papers 2006-01-20
Image Based Source Camera Identification Using Demosaicking: This paper represents the spatially periodic inter-pixel correlation due to color filter array interpolation in a quadratic form. Based on this, a coefficient matrix is obtained for each color channel, whose principal components are extracted and fed to feed-forward Back Propagation networks for source camera identification. Experiments demonstrate the efficacy,...; Tags: Shanghai Jiao Tong University, Camera; White papers 2006-07-09
Distributed Data Mining: Why Do More Than Aggregating Models: This paper deals with the problem of mining large distributed databases. The paper shows that the aggregation of models, i.e., sets of disjoint classification rules, each built over a subdatabase is quite enough to get an aggregated model that is both predictive and descriptive, that presents excellent prediction capability and...; Tags: Model, Universite Laval, Data Mining, Business Intelligence, Productivity, Marketing Research, Databases, Enterprise Software, Software, Data Management, Marketing; White papers 2006-12-05
