Hyperspectral library for Python

Hyperspectral library for Python

Presentation

PySptools is the Python Spectral Tools project. It is hosted on http://sourceforge.net/projects/pysptools/

You can go to the online documentation at http://pysptools.sourceforge.net/. The online documentation is updated regularly.

PySptools is a python module that implements spectral and hyperspectral algorithms. Specializations of the library are the endmembers extraction, unmixing process, supervised classification, target detection, noise reduction, convex hull removal and features extraction at spectrum level.

Dependencies

* Python 2.7 or 3.x
* Numpy, required
* Scipy, required
* scikit-learn, required
* SPy, require, version >= 0.17
* Matplotlib, required
* CVXOPT, optional, to run FCLS
* IPython, optional, if you want to use the display feature

The library is developed on the linux platform, with anaconda2-2.4.1 and anaconda3-2.4.1.

Installation

PySptools can run under Python 2.7 and 3.5. It has been tested for these versions but can probably run under others Python versions.

Note: The HSI cubes are, in general, large and the 64 bits version of Python is recommended.

The latest release is available at these download sites:

• pypi https://pypi.python.org/pypi/pysptools
• sourceforge http://sourceforge.net/projects/pysptools/

Manual installation

To install download the sources, expand it in a directory and add the path of the pysptools-0.xx.x directory to the PYTHONPATH system variable.

Distutils installation

You can use Distutils. Expand the sources in a directory, go to the pysptools-0.xx.x directory and at the command prompt type 'python setup.py install'. To uninstall the library, you have to do it manually. Go to your python installation and in the Lib/site-packages folder simply removes the associated pysptools folders and files.

and science articles.

To run the test cases, download data1 and expand it in the pysptools directory. But this is less true for the current version. The test cases will be reorganized in a future version.

In hope that this program is usefull.
