Method and apparatus for image processing employing image segmentation using tokenization |
摘要 |
A method for image processing including segmenting document images into text and continuous tone regions is provided. The method uses a token shape comparison and resultant data (e.g. shape recurrence) to determine which high-contrast regions of the image correspond to text or other symbols. The identified text is then separated from the image and processing ensues.
