Investigators at Northeastern University Describe Findings in Image and Video Processing

March 4, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Image and Video Processing have been published. According to news reporting originating in Boston, Massachusetts, by VerticalNews journalists, research stated, "Atmospheric InfraRed Sounder images are a type of ultraspectral images that are good candidates to compression as they include several thousand bands that account for well over 40 MB of data per single cube. As part of most prediction based compression schemes, there is a preprocessing stage in which a reversible band ordering process is included to maximize spectral band correlation."

The news reporters obtained a quote from the research from Northeastern University, "In this paper, we analyze, compare, and propose novel improvements to different band ordering and correlation estimation techniques in the context of ultraspectral image compression. In order to measure the performance of these methods, we also introduce a new metric based on comparing a given sequence of spectral bands to the corresponding optimal one."

According to the news reporters, the research concluded: "Finally, we apply the techniques presented in this paper to a real compression algorithm in order to obtain compression rates as a function of band ordering and correlation factors while determining the best scenario."
