Effect of Speckle Filtering On SAR High Resolution Data for Image Fusion

Image fusion is the process of combining significant information from two or more images into a single image. The resulting image will be more informative than any of the input images. Image fusion is powerful technique for merging similar sensor and/or multi-sensor images to enhance the information. In remote sensing applications, the increasing availability of space borne sensors gives a motivation for different image fusion algorithms. Several situations in image processing require high spatial and high spectral resolution in a single image. Most of the available equipment is not capable of providing such data convincingly. The image fusion techniques allow the mixing of different information sources. The fused output image can have complementary spatial and spectral resolution characteristics.
