Title:
SYSTEM FOR FINGERPRINT IMAGE RECONSTRUCTION BASED ON MOTION ESTIMATE ACROSS A NARROW FINGERPRINT SENSOR
Document Type and Number:
WIPO Patent Application WO/2005/109321
Kind Code:
A1
Abstract:
In accordance with an embodiment of the present invention, an efficient and accurate system and method are described for detecting a fingerprint from swipe sensor system. A swipe sensor module (104) is coupled to a microprocessor module (102). The swipe sensor module (104) collects fingerprint image data as a plurality of frames and passes the frames of data to the microprocessor module (102). The microprocessor module (102) assembles the frames of data into a complete image of the fingerprint that is cropped and processed to remove noise and artifacts. The cropped image is used to generate a template in a first instance and to compare an extracted portion of the cropped image to existing templates in a second instance.
