MSSWD - Multi-Spectral Ship Wake Dataset

The Multi-Spectral Ship Wake Dataset (MSSWD) is a dataset designed for ship wake detection in multi-spectral satellite imagery. It is structured as follows: - Source: 661 image chips derived from 50 Sentinel-2 images, captured by the Multi-Spectral Instrument (MSI) at 10-meter resolution across the visible, near-infrared (VNIR), and short-wave infrared (SWIR) spectral bands. The chips come already pre-processed to highlight sea surface features by using a Contrast Limited Adaptive Histogram Equalization (CLAHE) technique. - Content: The dataset includes 1059 ship wakes, with various configurations such as: - Single ship wakes - Multiple ship wakes - False wakes (e.g., airplane wakes, sea crests) - Sea clutter with no visible wakes - Wake Characteristics: Diverse patterns of ship wakes are captured, including: - Vertical, horizontal, and tilted wakes - Cluttered sea scenes - Partial occlusions due to cloud cover - Data Quality: Focused on quality over quantity, MSSWD reflects real-world complexity by collecting data in congested, crowded maritime environments. - Data Labelling: Manually annotated using polygonal annotations to delineate wake contours, which allows: - Instance segmentation - Enhanced refinement during data augmentation
