The sofware library includes a set of classes for implementing compression of vector large data streams using sparse coding in combination with streaming coreset computation. It also incldues an application program that demonstrates the compress/decompression of scalar volumetric data.
The code has been used, in particular, for implementing systems for real-time exploration of massive static and time-varying rectilinear scalar volumes. See references below.
See INSTALL file for installation instructions and individual class documentation for more info. Additional documentation is availabile in Deliverable D6.2 on the TDM project deliverables web site.
