Description: A Rotation Region Proposal Network (RRPN)  is designed to generate inclined proposals with text orientation angle information. The angle information is used for bounding box regression to detect accurately oriented text proposals. The rotated region-of-interest pooling layer projects the proposals to a feature map for a text region classifier.
