Application of geometric flow and bandelet coefficient combining method to image fusion

摘要

Based on the theory of Bandelet transformation, we use Beamlab200 toolbox and Matlab software, adopt new construction of geometric flow and Bandelet coefficient combination method, apply new introduction of smaller absolute value rules, and take advantage of usage of computer simulation to experiment image fusion to explore the coefficient combination method and new introduction of smaller absolute value rules for geometric flow and Bandelet and test effect of their application to image fusion. The result after the experiment proves that this method is superior than the Beamlab 200 toolbox method in terms of running time, convergence speed, standard deviation, signal-to-noise ratio, gradient and image effect. The method can be applied to repair damaged images and others according to the results.
