METHOD FOR DETECTING A DOCUMENT BOUNDARY |
摘要 |
A method for detecting a document boundary in a captured digital image depicting a hardcopy document on a background. Each color channel of the captured digital image is analyzed to determine a corresponding busyness metric representing a complexity level of the image data. The color channel having a lowest busyness level is selected and analyzed to detect a document boundary of the depicted hardcopy document. The detected document boundary can be used to perform a perspective correction process to determine a corrected digital image where the depicted document has a substantially rectangular boundary. |
