The methods of color_space transformation, ratio transformation and the correlation coefficient have been discussed in this paper for image fusions of SAR and TM band 3,4,5 respectively, in order to get the enhanced images. The details of techniques and processing methods during the image fusion have been introduced. Because of the obvious noises within SAR image, the δ filtering as preprocessing for noise removal before image fusion should be considered. The image quality evaluations after fusion could be implemented by visual effects, eutropy, average gradiant and standard deviation. The results show that the informations of fusion images are richer and clearer than the raw ones'.
