Spectral Processing Extension 1.0.0rc1 has been released on February 12th, 2010.
This release is the first release candidate for 1.0.0. This release is marked as "not for production". The current plan is to allow two weeks for the community to validate this release. If you find any major issues please report them to our bug and issue tracker. If no major issues have been identified by March 1st, then creation of 1.0.0 will proceed. Currently, 1.0.0 is scheduled to be available on March 3rd and it will be a production release and can be used to create production products. Please download and validate this release to help ensure 1.0.0 is a great release!

New Features
- Provide a importer to load Landsat TM and Landsat ETM+ files into Opticks.
- Provides the following algorithms to convert an image from radiance to reflectance: Empirical Line Method (ELM) and Internal Average Relative Reflectance (IARR).
- Provides the following algorithms to find signatures matches in an images: Spectral Angle Mapper (SAM) and Constrained Energy Minimization.
- Provides a specialized "Signature Window" plot to display and manipulate signatures including the ability to generate signatures from a scene (either a single pixel or a user created Area of Interest).
- Provides a specialized "Range Profile" plot to display and then manipulate signatures in order to better align them.
- Provides a number of methods to resample a signature to match the wavelengths of an image before applying a signature matching algorithm.
- Provides a capability to build libraries of many signatures which can then be exported to an ENVI Signature Library file.
- Provides some additional importers and exporters for both individual signatures and signature sets.
- Provides the Minimum Noise Fraction Algorithm (MNF) in order to preprocess an image and remove extraneous noise in order to improve later signature matching algorithms.
Supported Opticks Versions
- This extension is supported in any version of Opticks 4.3.X that is Opticks 4.3.3rc1 or later.
