cycxhw_to_yxyx(...): Converts box center coordinates plus height and width terms to corner.

decode_boxes(...): Decode boxes.

denormalize_boxes(...): Converts boxes normalized by [height, width] to pixel coordinates.

encode_boxes(...): Encode boxes to targets.

filter_boxes(...): Filter and remove boxes that are too small or fall outside the image.

filter_boxes_by_scores(...): Filter and remove boxes whose scores are smaller than the threshold.
