Hi,

I just started ith Object Detection and I'm finding this book incredibly useful. As I'm now going throug the function "anchor_boxes" withon the script "layer_utils.py", I do not completely understand why the tensor of anchor boxes has this dimensions:
tensor = (feature_map_height, feature_map_width, n_boxes, 4)

I do not understand why the last dimension is size 4. What is the reason behind it?

Thank you!

I close it.
