Hello! It sounds like you're looking to automate the process of saving detections with low confidence scores for further annotation. Currently, YOLOv8 does not directly output detections in YOLO annotation format, but you can easily extract this information from the Results
object and format it accordingly.
Here's a quick example of how you might do this in Python:
from ultralytics import YOLO
# Load your model
model = YOLO('path/to/your/custom_model.pt')
# Run predictions
results = model.predict(source='path/to/your/images')
# Save low confidence detections
threshold = 0.25 # Set your confidence threshold
for result in results:
for box in result.boxes:
if box.conf < threshold:
with open('low_conf_detections.txt', 'a') as file:
# Format: class x_center y_center width height
x_center, y_center, width, height = (box.xywh / result.orig_img.shape[1::-1]).tolist()
file.write(f'{int(box.cls)} {x_center} {y_center} {width} {height}\n')
This script will append the low confidence detections to a text file in the YOLO format. You can adjust the threshold
as needed to capture the detections you're interested in reviewing. Hope this helps!
