Claim One:
1. A method for extracting features from an image for use in a computing device, the method comprising: producing Gaussian Scale Space (GSS) images in the type of a pyramid from the image inputted to the computing device; performing a Scale Normalized Laplacian Filtering on the GSS images; detecting interest points from the images that are subject to the Scale Normalized Laplacian Filtering; and extracting features of the image using the detected interest points, wherein the detecting interest points comprises processing three adjacent GSS images using one storage area for GSS images, one storage area for SCLoG (Scale Normalized Laplacian of Gaussian) images, one storage area for gradients, and a plurality of temporary storage areas, and wherein the processing three adjacent GSS images includes copying and calculating the GSS images and the SCLoG images into the temporary storage areas.
