    The sixth annual Space and Earth Science Data Compression Workshop and the third annual Data Compression Industry Workshop were held as a single combined workshop. The workshop was held April 4, 1996 in Snowbird, Utah in conjunction with the 1996 IEEE Data Compression Conference, which was held at the same location March 31 - April 3, 1996. The Space and Earth Science Data Compression sessions seek to explore opportunities for data compression to enhance the collection, analysis, and retrieval of space and earth science data. Of particular interest is data compression research that is integrated into, or has the potential to be integrated into, a particular space or earth science data information system. Preference is given to data compression research that takes into account the scien- tist's data requirements, and the constraints imposed by the data collection, transmission, distribution and archival systems

    Evaluation of digital image compression algorithms for use on lap top computers

    A technique for the evaluation of image compression algorithms was developed. This technique was then applied in the evaluation of six image compression algorithms (ARIDPCM, ISO/JPEG DCT, zonal DCT, proprietary wavelet, proprietary sub-band coding and the proprietary DCT). Of the six algorithms evaluated, the Wavelet algorithm performed the best on average in image quality at all bit rates. The JPEG DCT was concluded to be the most useful algorithm because of its performance and the advantages that come with being an international standard
