SPIE Conference on advanced signal processing algorithms, architectures, and implementations vIII
作者: Cohen, L CUNY Hunter Coll New York NY 10021 USA
We generalize the concept of the autocorrelation function to arbitrary physical variables and show how it can be used to define a local autocorrelation function. Using the local autocorrelation function we develop a n... 详细信息

作者: Chan, TF Zhou, HM Univ Calif Los Angeles Dept Math Los Angeles CA 90095 USA
In this report, we propose combining the Total variation denoising method with the high loss wavelet compression for high noise level images. Numerical experiments show that Tv-denoising can bring more wavelet coeffic... 详细信息

SPIE Conference on advanced signal processing algorithms, architectures, and implementations vIII
作者: Chu, MT Funderlic, RE Plemmons, RJ N Carolina State Univ Dept Math Raleigh NC 27695 USA
We consider two general procedures for constructing the nearest approximation of a given matrix by one with any lower rank and any linear structure. Nearness can be measured in any matrix norm. Structured low rank mat... 详细信息
