Description: A Rotation Region Proposal Network (RRPN) [8] 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.
