METHOD AND APPARATUS FOR PORTABLY RECOGNIZING TEXT IN AN IMAGE SEQUENCE OF SCENE IMAGERY |
摘要 |
An apparatus (100, 1200) and a concomitant method for detecting and recognizing text information in a captured imagery. The present method transforms the image of the text to a normalized coordinate system before performing OCR, thereby yielding more robust recognition performance. The present invention also combines OCR results from multiple frames, in a manner that takes the best recognition results from each frame and forms a single result that can be more accurate than the results from any of the individual frames. In one embodiment, the present invention is a portable device that is capable of capturing imagery and is also capable of detecting and extracting text information from the captured imagery. The portable device contains an image capturing sensor, a text detection module, an OCR module, a storage device and means for presenting the output to the user or other devices. |
