Image fusion based on weighted 】 and pyramid image fusion with matlab code

1 Introduction

Based on the powerful image processing toolbox function of Matlab, the images are fused by the weighted average method, the Laplace pyramid transform method and the wavelet transform method, and then the quality of the fusion results is evaluated by the corresponding evaluation indicators in the objective evaluation method.Evaluation.Experiments show that the wavelet transform method has the best image fusion effect.
