Hello everyone.
I need to retrieve the location of the bounding box relative to the center of the image.
for that, I use results.boxes[0].xywh but I’m not sure where x and y are measured from.
are they measured from the top-left of the image or from the center of the image?
couldn’t find it in the docs. tnx! 
Hello! 
Great question! The results.boxes[0].xywh method returns bounding box coordinates in the format [x_center, y_center, width, height]. Here, x_center and y_center represent the center of the bounding box, and these values are measured from the top-left corner of the image, not the center.
If you want to calculate the position relative to the center of the image, you can do so by subtracting half of the image’s width from x_center and half of the image’s height from y_center. Here’s a quick example:
image_center_x = image_width / 2
image_center_y = image_height / 2
relative_x = x_center - image_center_x
relative_y = y_center - image_center_y
This will give you the coordinates of the bounding box center relative to the image center. For more details on handling bounding boxes, you might find the Ultralytics documentation helpful.
Feel free to ask if you have more questions! 
For images coordinates in general, the convention is to have origin at the top-left.
Thank you!
Thank You!
