Build an Image Annotation Tool for Object Detection Using Python & OpenCV
📌 OpenCV Image Annotation Tool (Python)
In this video, I build a simple image annotation tool using Python & OpenCV.
You can draw bounding boxes with the mouse, undo annotations, and save labels to a text file—useful for object detection dataset creation.
🔹 Features
Draw bounding boxes using mouse drag
Live preview while drawing
Undo last box (z)
Save labels (s)
Quit tool (q)
🔹 Label Format
class_id x1 y1 x2 y2
🔹 Use Cases
Object Detection datasets
YOLO / Computer Vision projects
Learning OpenCV mouse events
