hiproc 0.7.0

A library to help process HiRISE EDRs with ISIS.

hiproc

A library to help process HiRISE EDRs with ISIS.

• Free software: Apache 2 License

Features

• TODO: Complete testing against Perl Pipelines.

External Dependencies

These programs use as much ‘vanilla’ Python 3 as possible.

However, it does depend on the following:

• pvl library (https://pvl.readthedocs.io)

• kalasiris library (https://kalasiris.readthedocs.io)

• gdal

• numpy

• scipy

• matplotlib

Warning !

The algorithms based on the HiRISE Processing Pipelines were emulated and tested locally, but the results of each pipeline have not been tested directly against the results of the HiRISE Processing Pipelines, and this warning will remain until I have done so. As a result, I would not particularly ‘trust’ anything produced by these programs at this time, and consider these algorithms a work-in-progress.

These programs have been tested against their upstream Perl counterparts:

• EDR_Stats: Verified!

  Really just runs hi2isis so no surprise here.

• HiCal: Verified.

  Upstream is undergoing change, needs to be re-verified once upstream settles down.

• HiStitch: not verified

• HiccdStitch: not verified

• HiColorInit: not verified

• HiJitReg: not verified

• HiSlither: not verified

• HiColorNorm: not verified

• HiBeautify: not verified

• HiPrecisionInit: not verified

• HiNoProj: not verified

• HiJACK: not verified

Documentation

Full documentation for hiproc is available, including information on the processing flow of the various available programs, and each program is self-documenting via their -h argument.

Due to the interaction with ISIS and GDAL, please read the installation instructions carefully.

Contributing

Feedback, issues, and contributions are always gratefully welcomed. See the contributing guide for details on how to help and setup a development environment.

Naming

The ISIS software has a number of processing or “proc” programs (mocproc, thmproc, etc.) that are meant to be run to process raw images to higher-level, more usable versions. Naming this library hiproc is an echo to that. There is a hiproc program that is available after installation that provides a streamlined one-stop-program, but this package provides a great deal more.

Unreleased

0.7.0 (2021-06-15)

Added

• Improved documentation

• environment.yml for conda development

• Added Python-based multiprocessing capabilities to EDR_Stats, HiCal, and hiproc.

Changed

• Incorporated changes from upstream to HiCal to make bitflip and lisfix settings on by default.

Fixed

• resolve_jitter output header lines properly commented, now doesn’t bomb HiJACK’s run of hijitter.

• now, additionally supporting ISIS 4.1.1 through 5.0.0

• Upstream addressed a bug in analyze_cubenorm_stats() that we had noticed, so now fixed here, too.

• MANIFEST.in did not properly include the “data” directory, so that was a problem.

0.6.1 (2021-03-23)

Added

• lisfix will return a non-zero exit code if it chooses not to fix the input cube.

Changed

• Updated documentation in various places.

0.6.0 (2021-03-18)

Added

• More complete documentation for the programs and their parameters.

Changed

• Implemented better handling for configuration files so that they will get distributed with the package.

0.5.0 (2021-03-05)

Added

• lisfix: Added the lisfix module.

• bitflips: Sometimes the very end of the histogram (although not a formal minima) is the appropriate choice, and is now considered.

• bitflips: Added capability to ignore minor maxima at the ends of the histogram to “roll down” to a better solution.

Changed

• name change of project from pyrise to hiproc.

• bitflips: Changed the default medstd_limit from 300 to 400 DN.

Fixed

• bitflips: There were a variety of edge cases that resulted in errors. The appropriate guardrails, handlers, and recovery logic has now been added.

• HiStitch: The equalize and balance parameters cannot both be true.

0.4.0 (2020-09-22)

• Tremendous amount of re-working in bitflips to improve performance.

• Format cleanup

0.3.0 (2020-05-16)

• Confirmed that EDR_Stats and HiCal produce identical output cubes.

0.2.0 (2020-05-06)

• Updated with bit-flip correction.

0.1.0 2020-03-21

• First shared on GitHub
