It's YOLO, you only look once.
So how much information you look once depends on how large the patch size is.
Simply change imgsz
for training, but also be aware of the GPU memory limit.
yolo detect train model=yolov8m.pt data=dataset.yaml imgsz=1088

@ixez hi there!
Thank you for reaching out. You're absolutely right that resizing images can sometimes lead to a loss of detail, especially when the target size is significantly smaller than the original. Here are a few suggestions to help mitigate this issue:
-
Increase Image Size (
imgsz
): As you mentioned, increasing theimgsz
parameter can help preserve more details. However, be mindful of your GPU memory limits. You can try a larger size like1088
or even higher if your hardware allows it:yolo detect train model=yolov8m.pt data=dataset.yaml imgsz=1088
-
Data Augmentation: Sometimes, applying data augmentation techniques can help the model learn to recognize objects even when details are slightly blurred. Techniques like sharpening, contrast adjustment, and noise addition can be beneficial.
-
High-Resolution Training: If GPU memory is a constraint, consider training on high-resolution images and then using a lower resolution for inference. This way, the model learns from more detailed images.
-
Multi-Scale Training: YOLOv8 supports multi-scale training, which can help the model generalize better across different image sizes. You can enable this by setting
multi_scale=True
in your training command. -
Check Image Quality: Ensure that the images in your dataset are of high quality and properly annotated. Sometimes, the issue might be with the dataset itself rather than the resizing process.
If you continue to face issues, please provide a minimum reproducible example so we can investigate further. You can find more details on creating a reproducible example here.
Feel free to reach out if you have any more questions or need further assistance. Happy training! 😊
