UIBK Avalanche Dataset

UIBK Avalanche Dataset Dataset of 4090 labelled avalanche photographs. Each photograph in the dataset was assigned to one of four categories: glide, loose, slab, or none. These labels refer to the different avalanche release mechanisms: glide, loose-snow, and slab, with none indicating the absence of avalanches. In addition, avalanche experts outlined each visible avalanche with a polygonal bounding box and assigned it a single label of glide, loose, or slab. The photographs were taken in the field in the winters of 2000/2001 - 2021/2022 and each image has the date and approximate location at which it was taken in the image name. Most photographs in the dataset were taken from the ground: additional images from low-flying helicopters were included only if the annotators deemed that they could feasibly have been taken by webcams. Accompanying code for training ResNet, VGG, and YOLOv3 models to detect avalanches is available at github.com/j-f-ox/avalanche-detection Folders annotations # Polygonal and rectangular bounding boxes for each avalanche image glide loose slab images # The .jpg images sorted by overall image label glide loose none slab test.txt # Test images train.txt # Training images Label Distribution The images folder contains 716 glide, 416 loose, and 1887 slab avalanche photographs and a further 1071 "none" images without visible avalanche regions The dataset contains a total of 2489 annotated glide avalanches, 1827 loose-snow avalanches, and 2912 slab avalanchesUIBK雪崩数据集（UIBK Avalanche Dataset） 本数据集包含4090张带标注的雪崩照片。数据集中的每张照片被归类为以下四个类别之一：滑动雪崩（glide）、松散雪雪崩（loose，对应loose-snow）、板状雪崩（slab）以及无雪崩（none）。上述标签对应不同的雪崩启动机制：滑动雪崩、松散雪雪崩与板状雪崩，其中“无雪崩”标签表示图像中不存在雪崩区域。此外，雪崩专家会为每一处可见的雪崩绘制多边形边界框，并为其标注滑动雪崩、松散雪雪崩或板状雪崩中的单一类别。 所有照片均拍摄于2000/2001至2021/2022冬季的野外场景，每张图片的文件名中包含其拍摄日期与近似拍摄位置。数据集中绝大多数照片为地面拍摄所得，仅当标注人员认为该低空直升机拍摄的照片可通过网络摄像头等效拍摄时，才会被纳入数据集。 用于训练ResNet、VGG、YOLOv3模型以实现雪崩检测的配套代码可在github.com/j-f-ox/avalanche-detection获取。 ### 文件夹结构 annotations：存储每张雪崩图像的多边形与矩形边界框，其下包含glide、loose、slab三个子文件夹 glide loose slab images：按图像整体标签分类存储的.jpg格式图像，其下包含glide、loose、none、slab四个子文件夹 glide loose none slab test.txt：测试集图像列表文件 train.txt：训练集图像列表文件 ### 标签分布 images文件夹内包含716张滑动雪崩类照片、416张松散雪雪崩类照片、1887张板状雪崩类照片，以及额外1071张无可见雪崩区域的“无雪崩”类图片。 本数据集总计包含2489处已标注的滑动雪崩、1827处松散雪雪崩以及2912处板状雪崩。
