ECE Colloquium: Sparse Representation of Multispectral Images and Application to Remote Sensing
Start Date: 6/19/2014Start Time: 2:00 PM
End Date: 6/19/2014End Time: 3:00 PM



Abstract

Recently, there have been important developments on sparse representation of signals and images.  It also attracted a lot of attention among researchers in the area of signal and image processing, and is applied to many important applications, including data acquisition, image compression, image restoration, multispectral image representation, etc.  There are three major problems in researches related to sparse representation of signals and images: How to sparsely represent an image, What are characteristics of data after it is sparsely represented, and What we can do with it after a sparse representation is performed on an image.  In this seminar, I will introduce some of our recent research works, which address all three major problems of sparse representation. Specifically, it will include major techniques such as Dictionary learning, Total variation, and Compressed sensing in this talk.  Some of interesting results of our work will also be presented and explained.
