Lifebuoy Underwater Dataset for Object Detection

Overview

This dataset contains images of virtual underwater lifebuoy for object detection tasks. It can be used to train and evaluate object detection models.

Demo Example:

Lifebuoy Underwater Detection Video

Video is available on video/lifebuoy_underwater_detection.mp4 or by clicking the image youtube link.

Dataset Structure

Data Instances

A data point comprises an image and its object annotations.
