Patent ID: 7831093

Claim:
A method for calculating photo and text separation performance to evaluate the performance of a photo and text separation result by performing a photo and text separation on an original image and using a photo and text separation algorithm, said method comprising steps of: (A) generating a standard block attribute file, wherein the step of generating said standard block attribute file includes the sub-steps of: (A1) displaying said original image on a monitor; (A2) performing said photo and text separation on said original image by using said photo and text separation algorithm, thereby outputting said photo and text separation result; (A3) dividing said photo and text separation result into a plurality of blocks, and marking each block with an attribute symbol designating each block as a text block, a photo block or a border block according to the attributes thereof; (A4) changing the attributes of some blocks by an examiner; and (A5) generating said standard block attribute file; (B) comparing said photo and text separation result with said standard block attribute file so as to display a photo and text separation performance table; and (C) wherein said photo and text separation performance table includes data associated with text block identification performance, picture block identification performance, border block identification performance and correct ratio.
