Questions tagged [bounding-box]

A Bounding Box is the smallest box that encloses a geometry. There are two common classes of Bounding Boxes that are employed: Oriented Bounding Boxes (OBB), and an Axis-Aligned Bounding Boxes (AABB). Bounding boxes are commonly employed as a cheap way to approximate more complex geometries in a range of applications, including collision detection.

A minimum Bounding Box can also be referred to as the minimum bounding or minimum enclosing box.

Is there any in-browser online tool for marking bounded boxes of objects in images for training neural networks?

I want to create my own dataset for YOLOv3 Object Detection. It looks like there is a huge set of offline tools for marking bounded boxes, for example: Yolo_mark, Microsoft VoTT, LabelImg. Is there any zero-config online tool, which will work right…
