Title: A k-means based image compression method

Abstract: Compression algorithms are an important part of storing and delivering large images such as those obtained at high resolutions using cameras. We propose a lossy algorithm that uses iterative clustering algorithms to reduce storage requirements for images while still preserving quality in large images. Our algorithm is competitive with standard methods and provides a parsimonious model for representing the images.

Bio: Geoffrey Thompson is a PhD Candidate in the Department of Statistics at Iowa State University.  He has a BA in mathematics from the University of Chicago and an MS in Mathematics (Actuarial Science) from Roosevelt University. Prior to coming to Iowa State University, he worked in the insurance
industry. This talk is based on a paper that won a student paper award in the Statistical Computing Section at JSM.

After the presentation, there will be a short time for discussion and questions afterwards.
