20140112527 | SIMULTANEOUS TRACKING AND TEXT RECOGNITION IN VIDEO FRAMES - Architecture that enables optical character recognition (OCR) of text in video frames at the rate at which the frames are received. Additionally, conflation is performed on multiple text recognition results in the frame sequence.
