Isuue with the sizes of bounding boxes

[eladpar]

Hey! so when I publish images by the size 640x640 everything seems to be OK.
But when I publish an image with dimensions 1280x720 the bounding boxes get "smooshed" they don't fit not the 640x640 image nor do they fit 1280x720 image.
Of course I'm using the image dimension parameters in the launch file, but is there a hardcover dimensions somewhere? Except for the fact yolo works with 640x640..

In yolov5 issac ros I just used to push the 1280x720 image and it would get resized in the input of the yolonn
