# csiro-spectral-tools
A very small collection of tools for working with spectral data. Documentation for the various modules can be
found in the docs folder. I used to have a class for parsing TSG data but after Ben Chi (https://github.com/FractalGeoAnalytics/pytsg) wrote a much nicer and cleaner version I have adopted his instead. Nice work Ben.
I used to have spectral unmixing routines in here as well but have removed them as they were really a bit (read a LOT) adhoc. They may come back in the future.
There is some documentation that I created with Sphinx but alas I am not that adept at Sphinx. Regardless it can be found in the docs folder
## Pre Installation Requirements (only if you need to build the extension file for doing convex hulls)
1. setuptools >= 18.0
2. Cython
In regard to cython you will probably need to ensure you have a compatible C
compiler for your OS. Probably best to take a look at the [Cython documentation](https://cython.readthedocs.io/en/latest/index.html)
to see what is required there. Who knows you may already have one installed.
## Installation (assumimg you are not building the Cython extension and are simply using the prebuilt .c and .pyx files)
$ python setup.py install
## What is this?
This package is a small collection of tools that I have developed or had a need for over the years. The primary focus is to work with spectral reflectance data.
I have recently gone through it and cleaned it up and dropped a bunch of half finished stuff.
It does have a precompiled cython file in the csiro_spectral_tools/ext folder for performing upper convex hull corections. If you need to compile it yourself then you will need Cython installed and a C compiler. The compiled version is for python 3.10 and a 64 bit system.
I have tried various python only implementations of hull correction routines but haven't found them to be fast enough. I probably need to look closer at `qhull`. With that said their is python only hulls routine in the package.
Additionally, if you want to run the feature extraction method then you need to run your routine in a main guard. If you don't then it will not allow you to use the
multiprocessor component. This initself is not a bad thing and for small datasets (<20000 spectra I guess) it probably isn't needed anyway. If you are extracting features from spectral imagery however then not using the main guard and the main_guard=True keyword in csiro_spectral_tools.extraction.extraction.extract_spectral_features will run noticeably slower due to the large number of samples.
## Whats in the csiro_spectral_tools package?
It is comprised of a number of sub-packages.
1. ext (package): A Cython implementation for convex hulls.
The main file is the chulls.pyx file from which the chulls.c and chulls\*.pyd is generated. A setup file to regenerate the c and pyd files is also in there.
You can directly call the chulls.get_absorption method but its better to use the csiro_spectral_tools.hulls.convexhulls.uc_hulls method instead. This is a wrapper for the chulls one and as such has type hinting etc.
2. extraction (package): A module for extracting spectral feature information from spectra
from csiro_spectral_tools.extraction.extraction import extract_spectral_features
3. io (package): An module with a bunch of convenience spectral data parsers. The parse_numpy one is probably a bit dumb but whatever.
from csiro_spectral_tools.io import parse_tsg, parse_envi, parse_csv, parse_numpy
4. python_hulls (package): A pure python implementation of convex hulls (phulls) and a warpper for the cython extension when you really need speed.
from csiro_spectral_tools.hulls.phull import get_absorption
or,
from csiro_spectral_tools.hulls.convexhulls import get_absorption
