A Robust Approach of Sonar Image Feature Detection and Matching

This paper is concerned with Modulus Maximum of Wavelet Transform (MMWT) and a graph theoretic method. The methods are applicable to extracting features of seafloor sonar image and data association problems. We will first get image’s modulus and modulus’ direction matrix by MMWT method. And according to calculating modulus’ threshold, obtain the geometric… CONTINUE READING
