Christopher M. Brislawn

I work in Digital Signal Processing in the Modeling, Algorithms and Informatics Group at Los Alamos National Laboratory. My research interests are in signal and image processing applications of wavelets .

Projects:

One of the first projects I worked on at LANL was designing the FBI's national standard for wavelet-based compression of their fingerprint database. Click the fingerprint icon for a project summary or browse the project's FAQ. Various documents and other materials about the Wavelet-Scalar Quantization standard can be downloaded from my WSQ anonymous ftp site.

A related project of interest is compression of wide-band RF signals collected by the Los Alamos satellites ALEXIS and FORTE. View an executive summary, or click the icon for the complete project report:

Another related activity is my role as the Lab's principal member on Technical Committee L3.2 of the InterNational Committee for Information Technology Standards (INCITS). This is the accredited US national body that participates in the ISO JPEG standards committee. View an executive summary on the JPEG-2000 standard currently under development or see a demonstration of LANL JPEG research on hyperspectral image coding in (MS Powerpoint 97, 3.6 MB) or (HTML with frames). I am currently editing Part 10 of the JPEG-2000 standard, "Extensions for Three-Dimensional Data and Floating Point Data."

Using MPEG motion estimation techniques, we have developed a video-based method for segmenting and identifying gaseous objects such as smoke plumes. View an executive summary on this project, complete with video demonstrations and a technical report.

Most recently, I've been working with John Hogden of CCS-3 on his technique of Maximum Likelihood Continuity Mapping (MALCOM).
