Abstract

In view of the fusion of SAR image and RGB image, different methods based on wavelet transform (WT) were studied. Based on WT, SAR images are fused with different channel of RGB images respectively. In order to suppress the speckle in SAR images, Speckle Reducing Anisotropic Diffusion (SRAD) and nonlocal mean filter (NLM) were introduced respectively. The image fusion effect was comprehensively measured by using several image quality indexes. The results show that WT and NLM are more helpful to improve the quality of image fusion.
