摘要

"Cases of detection of forgeries and images and the detection system".This is a process of detection of currency that detects seals in currency to prevent printing and prevent counterfeiting. Detected patterns of seal.The detector has the ability to identify whether an image contains one or several patterns of seal previously selected.The rotation is invariable in deviation and rotation -- a brand suspicion may be in any orientation and at any location within an image being tested.With the process: a device detector is trained off line using distinguishing marks is obtained with the result templates are generated and recorded for each of these brands diStintivas; images of sampling so suspicious marks are received by the detector device and the location and orientation of these marks are identified; these GAbaritos are subject to rotation and deflection for alignment of the listed templates with those marks; said templates and these marks are compared to beFinished if there is a match.A microprocessor is programmed to become acquainted with a plurality of distinguishing marks through training and to examine and detect sigils within documents tested.A memory stores the marks as templates.A reading device for scanning ("scanner") can be used with the system during training and detection to capture marks and images tested with marks for the use of the systemA.The resulting output can be used for controlled systems.Such as copying and reading devices for scanning ("scanners") to suspend any further action in the documents for which there are suspected of counterfeiting.
