Scene text recognition using a Hough forest implicit shape model and semi-Markov conditional random fields
Part-based character models are built in a Hough forest. The Hough forest robustly detects characters even if characters are highly degraded. Checking text line properties effectively remove false detections. Utilizing character models throughout the process raises end-to-end text recognition accuracy.
