Python module for hyperspectral image processing
SPy is currently developed for python 2.{6,7}. This enhancement will add support for python3. The current plan is to have a single code base that works for both python 2...
It would be great to support these optional header fields according to ENVI documentation: http://www.exelisvis.com/docs/EnterOptionalHeaderInformation.html#Set3 It's not going to be easy with the current memmap implementation.
There was a bug introduced with #135 relating to complex data types on windows. Windows does not have the complex256 dtype which causes this line to fail: Line 199 in...
The `PrincipalComponents` object returned by the `principal_components` function has eigenvalues in descending order; however, the `principal_components` attribute of the `GaussianStats` object returned by `calc_stats` is in ascending order. The latter...
@toaarnio @tboggs @donm @lewismc I am trying to visualize my hypercube data using `spectral` package and I follow the commands in the [main page][1] of spectral by `ipython --pylab=wx` and...
Loads basic info, does not load type, class and subclass some code using ignorefiles is not needed
Sometimes, we may get a singular matrix as the covariance. The [inv_cov](https://github.com/spectralpython/spectral/blob/0659ee71614455d99a80ffd4f5f5edd8d032608c/spectral/algorithms/algorithms.py#L746C7-L751) won't work. Is it correct to use `np.linalg.pinv` instead of `np.linalg.inv` for this kind of case?
The kernel matched filter (KMF) is defined in [Kwon & Nasrabadi (2007)](https://doi.org/10.1007/s11263-006-6689-3). Briefly, Given kernel function and target/background matrix, the KMFresponse is given by: ```math \begin{align} y(\hat{k}_r) = \frac{\hat{k}_t^T \hat{K}^{-2}...
