📚 Overview

SiaPy is a versatile Python library designed for processing and analyzing spectral images. It is particularly useful for scientific and academic purposes, but it also serves well for quick prototyping.

Built on top of the well-known spectral library, SiaPy extends its capabilities with additional features and functionalities.

Key Features

• Image Processing: Easily read, display, and manipulate spectral image data.
• Data Analysis: Perform in-depth analysis of spectral signatures using advanced analytical techniques.
• Machine Learning Integration: Select image regions for training models and segment images using pre-trained models.
• Camera Co-registration: Align multiple cameras and compute transformations across different camera spaces.
• Radiometric Conversion: Convert radiance to reflectance using reference panels.

To make some of the functionality more easily accessible, a command line interface (CLI) is also provided. See siapy-cli. However, the full functionality can be exploited by using the library directly.

💡 Installation

To install the siapy library, use the following command:

pip install siapy

For detailed information and additional options, please refer to the instructions.

💻 Examples

from pathlib import Path
from siapy.entities import SpectralImageSet

data_dir = "~/data"

header_paths = sorted(Path(data_dir).rglob("*.hdr"))
image_paths = sorted(Path(data_dir).rglob("*.img"))

imageset = SpectralImageSet.from_paths(
    header_paths=header_paths,
    image_paths=image_paths,
)
print(imageset)
