Abstract:In this paper is presented a pattern recognition methodology based on local feature extraction. The purpose of this system is to identify and locate, in three different scale pyramids, key points that represent relevant information of the image; this information is stored in a descriptor which is used to compares the key points of two images and know if they have similar information, or if they are the same images. This methodology uses the Haar wavelet transform to generate the three scale pyramids. This tran… Show more
