 # Introduction
-Here is the source code for an introduction to YOLO. We adopted the core concept of YOLOv1-YOLOv4 for this project, made the necessary adjustments, and then developed the new YOLOv1-YOLOv4. By learning how to use the well-known YOLO detector, we hope that newcomers can enter the field of object detection without any difficulty.
