## Choose when

### Choose YOLOv3-Object-Detection-with-OpenCV if…

- Tags unique to YOLOv3-Object-Detection-with-OpenCV: object-detection, pretrained-models, yolov3.
- When seeking a rapid, real-time solution for object detection in videos and images that benefits from predefined YOLOv3 configurations.

### Choose caer if…

- Tags unique to caer: augmentation, cuda, data-science, gpu.
- If you are working on projects that require scaling computer vision research efforts without excessive boilerplate code, Caer offers streamlined solutions.
- More GitHub stars (812 vs 358) - visibility, not fit.

## When NOT to use YOLOv3-Object-Detection-with-OpenCV

- In scenarios demanding highly detailed and accurate detections over speed, as competitors may offer better precision.
- For projects necessitating customization of the detection model beyond what pretrained YOLOv3 models allow.

## When NOT to use caer

- Avoid using caer if you are restricted to Python versions lower than 3.6, or when adherence to a specific older Python version is critical to your project.
- If compatibility with only open-source libraries is needed and CUDA support is not required, other more limited scope tools might be a better choice.
