Automate Game Scorekeeping with Vision AI
SUMMARY
This tutorial builds a real-time automated scorekeeping system for cornhole using a custom computer vision model and a Roboflow Workflow. The model detects bags, the board, and the hole from an overhead camera; the Workflow then applies game logic to map detections to zones, calculate the score, and

Improve Accuracy: Polygon Annotations for Object Detection
SUMMARY
Polygon annotations consistently outperform bounding boxes for object detection when objects have irregular shapes, because polygons eliminate background noise that bounding boxes include. An experiment comparing both annotation types, combined with augmentations (rotation, saturation, cutout, bounding box shear) and pretrained weight initialization, showed meaningful mAP gains at each step.
