12. ShipRSImageNet

• ShipRSImageNet contains over 3435 images with 17573 ship instances, annotated with both horizontal and orientated bounding boxes.
• The above 3435 images were obtained from various sensors, satellite platforms, locations, and seasons.
• Each image is around 930×930 pixels and contains ships with different scales, orientations, and aspect ratios.
• The spatial resolution of the images ranges from 0.12 to 6 m.
• These 3435 images were collected from:
  • The xView dataset (532 images).
  • The HRSC2016 dataset (1057 images).
  • The FGSD dataset (1846 images).
  • The Airbus Ship Detection Challenge (21 images).
  • Chinese satellites, such as GaoFen-2 and JiLin-1 (17 images).
• Ships in ShipRSImageNet are hierarchically classified into four levels (0-3) and 50 categories (49 ship types and "Dock").
• Level 0 distinguishes whether the object is a ship, namely "Class". Level 1 further classifies the ship object category, named as "Category". Level 2 further subdivides the categories based on level 1 ("Subcategory"). Level 3 is the specific type of ship, named "Type".
• The ShipRSImageNet was divided in training, validation and test sets which contain 64% (2198), 16% (550) and 20% (687) of the original images respectively.
• Each ship instance has a corresponding set of annotations which are:
  • A horizontal bounding box ↦ (xmin, ymin, xmax, ymax).
  • An oriented bounding box ↦ (xc, yc, w, h, θ).
  • A polygon annotation ↦ (x1, y1, x2, y2, x3, y3, x4, y4).
• The above annotations are available in Pascal VOC and MS COCO dataset formats.
