This PR updates YOLO pipeline to return bounding boxes scaled with respect to the original image rather than preprocessed image.
The solution included two changes:
Maintaining and propagating information on the original image sizes, this was done by adding a return value to the
_preprocess
function(the original image shape is returned) and propagating it topostprocessing
function via thepostprocessing_kwargs
Actual rescaling of the bounding boxes based on model input shape and original input shape
code to visualize bounding boxes:

Note: The failing test, seems to be from the following issue, but I haven't taken a deeper look yet
