FEZrs

FEZrs is a Python library developed by FEZtool for geospatial multispectral image processing and spectral analysis in remote sensing. It provides tools for image processing, feature extraction, spectral analysis, and analysis of geospatial raster data.

Project page: https://feztool.com/fezrs/

Features

✅ Apply various image filtering techniques (Gaussian, Laplacian, Sobel, Median, Mean)
✅ Contrast enhancement and edge detection
✅ Support for geospatial raster data (TIFF)
✅ Spectral analysis and calculation of remote sensing indices
✅ Tools for image classification, clustering, and feature extraction
✅ Designed for multispectral remote sensing and satellite imagery analysis
✅ Easy integration with Python-based web applications such as FastAPI

Documentation

Full documentation, API references, tutorials, and examples are available here: https://feztool-team.github.io/FEZdocs/libraries/fezrs/

📦 Installation

You can install FEZrs using your preferred Python package manager:

Using pip (PyPI)

pip install fezrs

Using conda (Anaconda)

conda install -c FEZtool fezrs

Using mamba (optional, faster conda alternative)

mamba install FEZtool::fezrs

Note: The mamba command requires Mamba to be installed. If it's not installed, use the conda command instead.

Usage

Example of applying a Gaussian filter to an image:

from fezrs import GaussianCalculator

gaussian = GaussianCalculator(
    tif_path="path/to/your/image_band.tif",
)

gaussian.execute(output_path="./your/export/path")
