To begin, we will clone an existing implementation of the YoloV9 research paper and install the required dependencies.
The repository contains pre-trained weight files for different configurations (yolov9-c.pt, yolov9-e.pt, gelan-c.pt, gelan-e.pt) of the YOLOv9 object detection model and its components. These weights are crucial for the model's ability to detect objects in images or videos.
Let's break down what each of these weights represents:
yolov9-c.pt: This weight file is designed for a balance between speed and accuracy. The "c" in the filename denotes a variant within the YOLOv9 model family, focusing on computational efficiency or a compact model size.yolov9-e.pt: The "e" in the filename denotes it is "enhanced" or "extended" version, offering higher accuracy. It is larger in size and requires more computational resources compared to other variants like yolov9-c.pt.gelan-c.pt and gelan-e.pt: These weights are associated with the GELAN (Generalized Efficient Layer Aggregation Network) architecture, which is part of the innovations introduced in YOLOv9. GELAN is designed to optimize parameter efficiency and improve the model's performance. The "c" and "e" in the filenames indicate different versions of the GELAN architecture, with each tailored for specific use cases or performance criteria. "c" is aimed at computational efficiency, while "e" aimed at enhancing performance.yolov9-c weightgelan-c weightIn our deployment, we would choose to deploy the model weight that is more computationally efficient. From the code cells above, you can observe that the gelan-c.pt model has a much faster inference time compared to yolov9-c.pt. Therefore, in this tutorial, we would deploy gelan-c.pt as it offers better computational efficiency.
The function begins by initializing the device and loading the pre-trained object detection model. It then downloads the image from the provided URL, preprocesses it by resizing and normalizing the pixel values, and converts it to a PyTorch tensor. This tensor is passed through the loaded model, and the resulting predictions are filtered using non-maximum suppression. For each remaining detection, the script scales the bounding box coordinates to match the original image dimensions, creates a Detections object from the Supervision library, and generates labels by combining the class IDs and confidence scores. Finally, it prints the generated labels to the console and returns them as a list.
