StampDetectDOCLIB Documentation

Current Version: StampDetect v1.0

StampDetectDOCLIB Library is a implementation of the stamp detection framework of Zhu etc. at Document Recognition and Retrieval XIII (SPIE 2006). It return a list of stamp candidate objects of DLEllipseCandidate type, which store information including zone region and confidence values of detected stamps.

The idea of the stamp detector is to robust locate elliptic objects within input images by formulating and characterizing connected edges using pair-wise second-order representation. This technique exploits the orientation information of pair of edges in order to infer the location and approximated area of the detected object using an effcient Hough transform voting scheme. This greatly speeds up detection of elliptic objects.

StampDetectDOCLIB library does not assume any prior information on the rough location of a stamp on the document page. Stamp detection is run on the entire document.


StampDetectDOCLIB Library is an add-on of DOCLIB. DOCLIB is being developed under contract by a collaboration between:
The Laboratory for Language and Media Processing
Unviersity of Maryland, College Park
and
Booz | Allen | Hamilton
