purpose of letterbox_transformer and possible bug

[zabir-nabil]

What is the purpose of letterbox_transformer used in the code?

In your test codes, you have processed the bounding boxes in the following manner,

for d in detections:
    x1, y1, x2, y2, score, cl = d
    if score < 0.3:
        break

Should the break statement be there or it should be a continue statement instead?

[see--]

break should be fine as the boxes are sorted by score: https://github.com/see--/keras-centernet/blob/master/keras_centernet/models/decode.py#L31

Edit: letterbox_transformer is from the original repo. It's how the images are resized.

Okay, didn't see the sorting part. Thanks.
