Question 27

+2 marksOne or more correct options

Which of the following statements correctly describe the Region Proposal Network (RPN) in Faster R-CNN?

Select all that apply.

A
The RPN is fully convolutional and shares its convolutional feature maps with the downstream detection network.
B
The RPN relies on an external Selective Search module to generate its region proposals.
C
At each sliding-window location, the RPN predicts objectness scores and box refinements relative to k predefined anchor boxes.
D
Anchors of multiple scales and aspect ratios allow the RPN to propose regions for objects of very different sizes and shapes.
