收藏资源简介:
Coralscapes 是一个用于珊瑚礁语义场景理解的大规模图像分割数据集,旨在促进对复杂珊瑚礁生态系统的自动化监测与分析。数据采集自38个不同的潜水点,共包含1030张高分辨率(1024×2048像素)的水下图像。所有图像均经过精细、一致且无主观猜测的像素级标注,涵盖了39个不同的底栖生物与非生物类别,包括多种活体、白化及死亡状态的珊瑚(细分至属级,如Acropora、Pocillopora、Stylophora)、海草、藻类覆盖的基质、海绵、海葵、巨蛤、海参、海胆、鱼类、其他动物,以及人类潜水员、垃圾、测绘工具、未知硬质基质、背景和过暗区域等。数据集被划分为训练集(777张图像,来自31个潜水点)、验证集(54张图像,来自2个潜水点)和测试集(199张图像,来自5个潜水点),每个样本包含原始图像和对应的分割标注图,总大小约为2.94 GB。该数据集适用于计算机视觉领域的图像语义分割任务,特别服务于海洋生物学、生态学和气候变化研究,可用于开发算法以自动识别和量化珊瑚礁健康状况、生物多样性和人类活动影响。
Coralscapes is a large-scale image segmentation dataset for semantic scene understanding of coral reefs, designed to facilitate automated monitoring and analysis of complex coral reef ecosystems. Collected from 38 distinct dive sites, the dataset contains a total of 1030 high-resolution underwater images with a resolution of 1024×2048 pixels. All images have undergone meticulous, consistent and objective pixel-level annotations, covering 39 distinct categories of benthic organisms and abiotic components. These include various live, bleached and dead corals (classified at the genus level, such as *Acropora*, *Pocillopora*, *Stylophora*), seagrass, algae-covered substrates, sponges, sea anemones, giant clams, sea cucumbers, sea urchins, fish, other animals, as well as human divers, garbage, survey equipment, unknown hard substrates, background and underexposed regions, among others. The dataset is split into a training set (777 images from 31 dive sites), a validation set (54 images from 2 dive sites) and a test set (199 images from 5 dive sites). Each sample includes the original image and its corresponding segmentation annotation map, with a total size of approximately 2.94 GB. This dataset is applicable to image semantic segmentation tasks in the field of computer vision, and specifically serves marine biology, ecology and climate change research. It can be used to develop algorithms for automatically identifying and quantifying coral reef health status, biodiversity and the impacts of human activities.
