OmniCloudMask

State-of-the-art cloud and cloud shadow segmentation for satellite imagery

OmniCloudMask example

OmniCloudMask is a Python library for cloud and cloud shadow detection in high to moderate resolution satellite imagery. It supports resolutions from 10 m to 50 m and works with imagery from Sentinel-2, Landsat, PlanetScope, Maxar, and other sensors with Red, Green, and NIR bands.

Key Features

  • Works with any imagery containing Red, Green, and NIR bands (10 m to 50 m resolution)

  • Any processing level (L1C, L2A, TOA, surface reflectance, etc.)

  • Validated on Sentinel-2, Landsat 8, PlanetScope, and Maxar imagery

  • Supports CUDA, MPS (Apple Silicon), and CPU inference

  • Optional confidence map export

  • Fast inference with multi-threaded patch-based processing

Output Classes

OmniCloudMask produces segmentation masks with four classes defined by the CloudSEN12 dataset:
