Description

Hi,

For every output detection [x1, y1, x2, y2], I would like to extract its corresponding region in the feature map output of the backbone of Faster-RCNN. Similarly, I want to extract the corresponding region in the feature map for the target (groundtruth) bounding boxes.

Can you point me to how this should be done?

Thank you.

Research direction

The issue does not name a file, test, or entry point. Start by locating the Faster-RCNN backbone feature-map output and the code representing final and target bounding boxes; check for an existing region-mapping utility, with completion defined as guidance or an accepted implementation for extracting both regions.
