“IMAGE COMPRESSION FOR INTERACTIVE APPLICATIONS WITH RANDOM ACCESS PATTERNS" Wednesday,
April 7, 2004 Abstract: Image data is central to many scientific and biomedical applications. These applications frequently extend the definition of "image" to include 3D volumetric and/or time series data and often involve both visual and automated image analysis. The sheer quantity of data produced by image sources presents challenges for data storage and transmission. Additional requirements for random access within datasets, interactive performance rates, and access to lossless data extend these challenges to the extent that they can not be satisfied by simple storage and retrieval of individual images using traditional formats. This presentation will provide an overview of basic image compression and information representation principals and show how they can be used to implement high performance systems for accessing and analyzing very large data sets. These methods have been extensively used in image analysis and research projects including the PSC Volume Browser. | ||
