MSSWD - Multi-Spectral Ship Wake Dataset

<p>The <strong>Multi-Spectral Ship Wake Dataset (MSSWD)</strong> is a dataset designed for ship wake detection in multi-spectral satellite imagery. It is structured as follows:</p> <p>- <strong>Source</strong>: 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.&nbsp;<br>&nbsp;&nbsp;<br>- <strong>Content</strong>: The dataset includes 1059 ship wakes, with various configurations such as:<br>&nbsp; - Single ship wakes<br>&nbsp; - Multiple ship wakes<br>&nbsp; - False wakes (e.g., airplane wakes, sea crests)<br>&nbsp; - Sea clutter with no visible wakes</p> <p>- <strong>Wake Characteristics</strong>: Diverse patterns of ship wakes are captured, including:<br>&nbsp; - Vertical, horizontal, and tilted wakes<br>&nbsp; - Cluttered sea scenes<br>&nbsp; - Partial occlusions due to cloud cover</p> <p>- <strong>Data Quality</strong>: Focused on <em>quality over quantity</em>, MSSWD reflects real-world complexity by collecting data in congested, crowded maritime environments.</p> <p>- <strong>Data Labelling</strong>: Manually annotated using polygonal annotations to delineate wake contours, which allows:<br>&nbsp; - Instance segmentation<br>&nbsp; - Enhanced refinement during data augmentation</p>
