    摘要: A method for reconstructing a fingerprint image from a plurality of frames captured from swipe fingerprint sensor is disclosed. The method is based on a motion estimation between consecutive fingerprint frames. Only a portion of each frame is used to obtain the motion estimate to minimize system resources necessary for reconstructing the fingerprint image.

    摘要: 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 is coupled to a microprocessor module. The swipe sensor module collects fingerprint image data as a plurality of frames and passes the frames of data to the microprocessor module. The microprocessor module 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.

    摘要: A system and method for efficiently performing a pattern matching procedure includes an enrollment manager that performs an image conversion procedure for converting an initial reference image into a reference template. The image conversion procedure may include at least one of a binarization procedure and a symmetrical reduction procedure to more efficiently utilize system resources such as processing requirements and memory requirements. A verification manager may then convert an initial test image into a transformed test image for combining with the foregoing reference template to produce a correlation image. The verification manager then analyzes matching characteristics of the correlation image to determine whether the initial test image matches the initial reference image.
