Abstract

A specific pattern detection method and apparatus for detecting whether an input image includes a specific pattern included in a bill, which may not be copied, and a copying machine including the same are provided. The specific pattern detection method includes extracting objects corresponding to marks of a specific pattern from an input image. The extracted objects are examined as to whether they have the same location relationship as the marks of the specific pattern. The objects having the same location relationship are verified to determine whether the objects are equal to the marks of the specific pattern. The specific pattern is determined as to whether the pattern exists in the input image from a result of the verification. Accordingly, the presence of the specific pattern in the input image can be instantly detected.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2005-0049697 filed in the Korean Intellectual Property Office on Jun. 10, 2005, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to image processing for pattern detection. More specifically, the present invention relates to image processing for a specific pattern detection method, and an apparatus for detecting whether an input image includes a specific pattern included in currency that cannot be copied, and includes the above image processing and / or Equipment copier. Background technique [0004] Recently, the performance of color copiers using color scanners has increased, thus increasing the risk of copying documents that should not be copied, such as currency or securities. In order to prevent copying of documents that should not be copied, color copiers generally use anti...
