Abstract
A method, system, and computer-readable medium containing computer-executable instructions are provided, for randomly relocating text character images of a scanned-in Asian character document to produce a shuffled image, wherein the meaning of text in the shuffled image is not understandable although individual characters forming the text in the shuffled image are recognizable. In one embodiment, the method includes generally four steps: (1) dividing an Asian character document image into a text image portion and a non-text image portion; (2) structuring the text image portion into a multiple resolution-level pyramid; (3) extracting shuffleable character images by analyzing the multiple-resolution-level pyramid; and (4) shuffling some or all of the extracted shuffleable character images to create a shuffled image. The shuffled (e.g., encoded) image can be reshuffled (e.g., decoded) back to the original text image portion of the Asian character document image, and combined with the non-text image portion to restore the Asian character document image.
