YOLO (You Only Look Once) represents a state-of-the-art, real-time object detection framework that has been widely implemented across domains such as surveillance, robotics, and autonomous navigation.
The release of YOLOv12 introduces substantial enhancements in computational efficiency and detection accuracy.
Before proceeding with the installation and execution of YOLOv12, ensure that your macOS system is equipped with the following software components:
pip: Python’s package management system; verify installation with:
pip3 --version
Python (≥3.x): Confirm its presence via:
python3 --version
YOLOv12 necessitates several foundational dependencies, which can be installed using either Homebrew or pip.
If Homebrew is available, install OpenCV with:
brew install opencv
For environments where Homebrew is unavailable or undesirable, install OpenCV through pip:
pip3 install opencv-python
Additionally, install auxiliary dependencies such as NumPy:
pip3 install numpy
Obtain the YOLOv12 source code by cloning its official GitHub repository:
git clone https://github.com/ultralytics/yolov12.git
Move into the repository’s root directory:
cd yolov12
YOLOv12 relies on the PyTorch deep learning framework alongside various auxiliary libraries. Install the requisite dependencies with:
pip3 install -r requirements.txt
To leverage pre-trained models for object detection, execute the following command to download the necessary model weights:
python3 models/download.py
Following successful installation, YOLOv12 can be applied to both image and video sources.
python3 detect.py --source path/to/your/image.jpg --weights yolov12.pt
Replace path/to/your/image.jpg
with the actual path to the image file.
python3 detect.py --source path/to/your/video.mp4 --weights yolov12.pt
Replace path/to/your/video.mp4
with the actual path to the video file.
python3 detect.py --source 0 --weights yolov12.pt
This command utilizes the default webcam as the video feed source.
python3 detect.py --source path/to/your/image.jpg --weights yolov12.pt --save-txt --save-conf
This variant of the command saves both bounding box coordinates and confidence scores to a text file.
python3 detect.py --source path/to/your/directory --weights yolov12.pt
This facilitates batch processing of all images within the specified directory.
The detected objects are annotated with bounding boxes and classification labels. To view the processed outputs, navigate to the designated results directory and open the images or videos using standard media viewers.
The YOLO framework is undergoing continuous refinements, with subsequent iterations expected to further enhance model efficiency and predictive accuracy. Researchers and developers should remain vigilant for updates to the YOLO ecosystem to maximize performance gains.
The implementation of YOLOv12 on macOS necessitates systematic installation of dependencies, acquisition of model weights, and configuration of runtime parameters.
