This is zfp, an open source C/C++ library for compressed numerical arrays
|
|
|
c1f560a |
that support high throughput read and write random access. zfp was written by
|
|
|
c1f560a |
Peter Lindstrom at Lawrence Livermore National Laboratory, and is loosely
|
|
|
c1f560a |
based on the algorithm described in the following paper:

zfp was originally designed for floating-point data only, but has been
|
|
|
c1f560a |
extended to also support integer data, and could for instance be used to
|
|
|
c1f560a |
compress images and quantized volumetric data. To achieve high compression
|
|
|
c1f560a |
ratios, zfp uses lossy but optionally error-bounded compression. Although
|
|
|
c1f560a |
bit-for-bit lossless compression of floating-point data is not always
|
|
|
c1f560a |
possible, zfp is usually accurate to within machine epsilon in near-lossless
|
|
|
c1f560a |
mode.
|
|
|
c1f560a |
|
|
|
c1f560a |
zfp works best for 2D and 3D arrays that exhibit spatial coherence, such as
|
|
|
c1f560a |
smooth fields from physics simulations, images, regularly sampled terrain
|
|
|
c1f560a |
surfaces, etc. Although zfp also provides a 1D array class that can be used
|
|
|
c1f560a |
for 1D signals such as audio, or even unstructured floating-point streams,
|
|
|
c1f560a |
the compression scheme has not been well optimized for this use case, and
|
|
|
c1f560a |
rate and quality may not be competitive with floating-point compressors
|
|
|
c1f560a |
designed specifically for 1D streams.
