More Information
Summary:A method and an apparatus for extracting feature points from a digital image are provided to improve image processing operation by reducing the time to extract feature points in a digital image. A plurality of processors share an original image into a plurality of domains and gradually perform blurring of the domains(210). The processors share the blurred images into a plurality of domains. The processors calculate the difference of Gaussian among a plurality of domains(220). Feature point data are generated based on the calculated difference of Gaussian(260).
