Handling characters the appearances of which are affected by three-dimensional (3D) rotation is a major challenge in Camera-Based Optical Character Recognition. Proper handling of these 3D rotated characters is expected to improve the performance of both detection and recognition of camera-captured characters. In this paper, we propose an efficient implementation of 3D rotation estimation for camera-captured characters. The proposed implementation requires small memory load and short… CONTINUE READING
