a library to characterize the data and check the compression results of lossy compressors
Z-checker-intaller can help you install everything (including compressors SZ and ZFP and other third-party libraries for plotting the figures). Z-checker-installer can be downloaded from http://github.com/CODARcode/z-checker-installer. Please read the user-guide of Z-checker for details.
For quick data compression analysis, you can use qca tool, which is included in this package. It can help you conveniently conduct data type conversion, file format conversion and quick data visualization, and compare the original data and decompressed data simply. The qca library can also be found on github (https://github.com/szcompressor/qca.git).
Please cite the following paper if you used Z-checker in your research/papers. Thanks!
