Description: An end to end text recognition framework (both text detection and recognition) was used. In detection part, we used modified SSD and improved NMS to detect both text confidence and its quadrilateral location. In recognition part, we used CNN+CTC. Finally, we refined the detection results using both the information of detection and recognition.
