ImageBounding Box
Using CVAT, I select the appropriate label class and draw boxes tightly around the object, ensuring minimal background inclusion while not cutting off any part of the object. For example, when annotating a person, the box should include the full visible body from head to toe, even if parts are partially occluded. I also pay attention to overlapping objects each object gets its own box, even if they intersect visually. Zoom and frame navigation tools are essential for accuracy, especially with small or distant objects. I frequently adjust box edges to align closely with object boundaries, and I rely on keyboard shortcuts to maintain efficiency without sacrificing precision.
