# ComfyUI Spectral

`ComfyUI Spectral` is a ComfyUI custom nodes library based on the [spectral](https://github.com/spectralpython/spectral), 

mainly used for visual processing of spectral files

## Install

You can choose to install it using [ComfyUI Manager](https://github.com/ltdrdata/ComfyUI-Manager)

Or manual installation:

1. clone to your `custom_nodes` folder

2. `cd ComfyUI_Spectral`

3. install dependencies `pip install -r reqirements.txt`

4. restart ComfyUI

## Notice

**_This repository is in the early stages of development, the functionality is not complete and may change in the future_**

## Workflow

## Nodes

- `Spectral Loader`: load spectral file, output `Spectral` object and preview image

- `ENVI Loader`: load imagery with associated ENVI header files and reading & writing spectral libraries with ENVI headers. 

## WIP

- ~~plot node~~

- ~~k-means node~~

- ~~calculate nodes~~

- pca node

- save node

- preprocess nodes

- improve performance
