| Abstract: | We explain a multi-scale analysis of wavelet theory and Mallat Algorithm.In view of the previous slow pace of implementation for MATLAB files,We propose a new mixed programming technique to call C++ source process using MEX file in MATLAB environment.We make a calculation and comparison of magnetic anomalies superposition of the sphere theoretical model,and using the method to decompose the aeromagnetic anomalies of a certain measured area and its surrounding areas,we get two orders of the typical character... |
