ABOships

The ABOships dataset consists of 9880 inshore and offshore images of maritime objects, belonging to one of the following categories: boat, cargoship, cruiseship, ferry, militaryship, miscboat, miscellaneous, motorboat, passengership, sailboat, seamark. Example images and definitions of these categories can be found in the reference paper. The total number of annotated objects is<br> 41,967 and includes 9 types of ships. The images were acquired from a collection of videos (format MPEG, with 720 p resolution at 15 FPS), extracting one image at every 15 s (or every 225 frames). The videos were acquired in the Finnish Archipelago, from a camera attached to a moving watercraft (waterbus – vesibussi in Finnish). The representation of labels for each category in the dataset is given by the following percentages, i.e. the percentage of images that include objects in each label category: seamark (37.89%), boat (20.58%), sailboat (38.88%), motorboat (41.11%), passengership (26.71%), cargoship (1.58%), ferry (9.56%), miscboat (28.30%), miscellaneous (1.30%), militaryship (25.90%), cruiseship (13.63%). A more detailed description of the datasets and instructions can be found in the PDF description file.ABOships数据集共包含9880幅海事物体的近岸与离岸图像，所有图像均隶属于以下类别之一：小型船艇（boat）、货船（cargoship）、游轮（cruiseship）、渡轮（ferry）、军用舰艇（militaryship）、杂类船艇（miscboat）、其他杂项（miscellaneous）、摩托艇（motorboat）、客船（passengership）、帆船（sailboat）、航标（seamark）。各类别的示例图像与类别定义可参见相关参考文献。该数据集的标注对象总数为41967，其中涵盖9类船舶。图像采集自一批MPEG格式的视频，此类视频分辨率为720p、帧率为15 FPS，每间隔15秒（或每225帧）提取一幅图像。视频拍摄于芬兰群岛海域，采集设备搭载于移动水上载体——水上巴士（芬兰语名为vesibussi）。数据集各分类的标签占比（即包含对应分类物体的图像占总图像数的百分比）如下：航标（seamark）37.89%、小型船艇（boat）20.58%、帆船（sailboat）38.88%、摩托艇（motorboat）41.11%、客船（passengership）26.71%、货船（cargoship）1.58%、渡轮（ferry）9.56%、杂类船艇（miscboat）28.30%、其他杂项（miscellaneous）1.30%、军用舰艇（militaryship）25.90%、游轮（cruiseship）13.63%。该数据集的更详细说明与使用指南可查阅配套PDF说明文档。
