Rotational region detection based on Faster-RCNN.

Overview

R2CNN_Faster_RCNN_Tensorflow

Abstract

This is a tensorflow re-implementation of R2CNN: Rotational Region CNN for Orientation Robust Scene Text Detection.
It should be noted that we did not re-implementate exactly as the paper and just adopted its idea.

This project is based on Faster-RCNN, and completed by YangXue and YangJirui.
