Local wavelet analysis for face recognition
Local wavelet analysis for face recognition

IEEE 15th signal processing and Communications applications conference
作者: Ekenel, Hazim Kemal Stiefelhagen, Rainer Univ Karlsruhe Dept Comp Sci Integrated Syst Labs D-76131 Karlsruhe Germany
In this paper we investigate the benefits of using local wavelet analysis to the face recognition problem. We examine two possible approaches to perform local wavelet analysis. In the first approach, discrete wavelet ... 详细信息

conference on wavelets - applications in signal and image processing IX
作者: Kamstra, L Ctr Math & Comp Sci NL-1090 GB Amsterdam Netherlands
The discrete wavelet transform was introduced as a linear operator. It works on signals that are modeled as functions from the integers into the real or complex numbers. Since many signals have finite function values,... 详细信息

4th conference on wavelet applications in signal and image processing
作者: Unser, M Thevenaz, P Aldroubi, A NIH BIOMED ENGN & INSTRUMENTAT PROGRAMNATL CTR RES RESOURCESBETHESDAMD 20892
We present examples of a new type of wavelet basis functions that are orthogonal across shifts, but not across scales. The analysis functions are low order splines while the synthesis functions are polynomial splines ... 详细信息

conference on wavelet applications in signal and image processing VI
作者: Meyer, FG Averbuch, AZ Stromberg, JO Coifman, RR Yale Univ New Haven CT 06520 USA
The main contribution of this work is a new paradigm for image compression. We describe a new multi-layered representation technique for images. An image is encoded as the superposition of one main approximation, and ... 详细信息

wavelets - applications in signal and image processing X conference
作者: Choi, H Baraniuk, R Rice Univ Dept Elect & Comp Engn Houston TX 77251 USA
In this paper, we link concepts from nonuniform sampling, smoothness function spaces, interpolation, and wavelet denoising to derive a new multiscale interpolation algorithm for piecewise smooth signals. We formulate ... 详细信息

作者: Lu, J APPLE COMP INC DEPT COMPRESS & SIGNAL PROCCUPERTINOCA 95014
Blocking artifacts are the most objectionable drawback of block-based image and video coders. We describe a novel technique for removing blocking artifacts via multiscale edge processing. The new technique exploits th... 详细信息
