Multispectral Demo Satellite Preprocessing Pipeline

A demonstration preprocessing pipeline for pushbroom multispectral optical instruments (under development).

Overview

This project implements an image processing pipeline for multispectral satellite imagery, with features including:

• Level 0 data processing and decoding
• Level 1 radiometric corrections including:
  • Non-uniformity correction (NUC)
  • Dark current correction
  • Denoising using various filters
  • Image sharpening and deconvolution
• Band co-registration
• Georeferencing
• Pansharpening

Requirements

• Python 3.x
• Required packages:
  • NumPy
  • OpenCV
  • GDAL
  • rasterio
  • scikit-image
  • matplotlib
  • Earth Engine API
