1. Tutorial Introduction 📖

YOLOv12 was launched in 2025 by researchers from the University of Buffalo and the University of the Chinese Academy of Sciences.YOLOv12: Attention-Centric Real-Time Object Detectors".

YOLOv12’s Breakthrough Performance

• YOLOv12-N achieves a mAP of 40.6% with an inference latency of 1.64 milliseconds on a T4 GPU, which is 2.1%/1.2% higher than YOLOv10-N/YOLOv11-N.
• YOLOv12-S beats RT-DETR-R18 / RT-DETRv2-R18, running 42% faster, using only 36% of computation, and reducing parameters by 45%.

📜 YOLO development history and related tutorials

Since its launch in 2015, YOLO (You Only Look Once) has been a leader in object detection and image segmentation.The following is the evolution of the YOLO series and related tutorials:

• YOLOv2 (2016): Introducing batch normalization, anchor boxes, and dimension clustering.
• YOLOv3 (2018): Using more efficient backbone networks, multi-anchors and spatial pyramid pooling.
• YOLOv4 (2020): Introducing Mosaic data augmentation, anchor-free detection head and new loss function. → Tutorial:DeepSOCIAL realizes crowd distance monitoring based on YOLOv4 and sort multi-target tracking
• YOLOv5 (2020): Added hyperparameter optimization, experiment tracking, and automatic export capabilities. → Tutorial:YOLOv5_deepsort real-time multi-target tracking model
• YOLOv6 (2022): Meituan open source, widely used in autonomous delivery robots.
• YOLOv7 (2022): Supports pose estimation for the COCO keypoint dataset. → Tutorial:How to train and use a custom YOLOv7 model
• YOLOv8 (2023)：Ultralytics released, supporting a full range of visual AI tasks. → Tutorial:Training YOLOv8 with custom data
• YOLOv9 (2024): Introducing Programmable Gradient Information (PGI) and Generalized Efficient Layer Aggregation Network (GELAN).
• YOLOv10 (2024): Tsinghua University introduced an end-to-end header and eliminated the non-maximum suppression (NMS) requirement. → Tutorial:YOLOv10 real-time end-to-end object detection
• YOLOv11(2024)：Ultralytics latest model, supporting detection, segmentation, pose estimation, tracking and classification. → Tutorial:One-click deployment of YOLOv11
• YOLOv12 🚀 NEW(2025): The dual peaks of speed and accuracy, combined with the performance advantages of the attention mechanism!

This tutorial uses RTX 4090 as the computing resource.

2. Operation steps🛠️

1. After starting the container, click the API address to enter the Web interface

The output of an object detector is a set of bounding boxes that enclose the objects in the image, along with a class label and a confidence score for each bounding box. Object detection is a good choice if you need to identify objects of interest in a scene but don’t need to know their exact location or shape.

It is divided into the following two functions:

• Image detection
• Video Detection

2. Image detection

The input is an image and the output is an image with labels.

Figure 1 Image detection

3. Video Detection

The input is a video and the output is a video with labels.
