This napari plugin is designed to hyper-spectral images of sediment cores. It is composed of three interfaces allowing the user to:

- import HDR images
- normalize the images using white and dark references
- mask unwanted regions
- perform spectral dimensionality reduction via minimum noise fraction analysis
- perform spatial dimensionality reduction based on pixel purity indices
- identify representative end-members by clustering pure pixels
- select relevant regions in spectra to compute absorption indices and create absorption maps 

### Pre-processing: Sediment widget

The sediment widget allows the user to import an HDR image and to normalize it using white and dark references. The widget also allows the user to mask unwanted regions of the images.

## Documentation

You can find a detailed documentation [here](https://guiwitz.github.io/napari-sediment).
## Installation

Create a conda environment and activate it. If you don't have conda installed you can for example install [miniforge](https://github.com/conda-forge/miniforge?tab=readme-ov-file#install).

    conda create -n sediment python=3.12 napari pyqt -c conda-forge
    conda activate sediment

Then you can install `napari-sediment` use:

    pip install napari-sediment

Or you can install the latest development version directly from the GitHub repository:

    pip install git+https://github.com/guiwitz/napari-sediment.git

On Windows, there is sometimes an issue installing PyTorch (needed for pixel classification). In this case we recommend the following:

    conda create -n sediment python=3.12 napari pyqt pytorch torchvision -c conda-forge
    conda activate sediment
    pip install git+https://github.com/guiwitz/napari-sediment.git

Contributions are very welcome. Tests can be run with [tox], please ensure
the coverage at least stays the same before you submit a pull request.
