Letterboxing is the process of resizing an image to a new shape while maintaining the aspect ratio of the original image. The new image is padded with a color to fill the remaining space.

Parameters:

frame -

letterboxed -

newShape -

color -

Returns:

resizeDetections

public List<NeuralNetworkPipeResult> resizeDetections(List<NeuralNetworkPipeResult> unscaled)

Resizes the detections to the original frame size.

Parameters:

unscaled - The detections to resize

Returns:

The resized detections
