Fusion of Satellite Images Using Multiwavelet Transform

The image sensors of the satellite can focus only on a particular operating range and environmental conditions, so it may not receive all the information necessary and each of the input images conveys important information that cannot be discarded. Scalar wavelet fusion scheme cannot possess all the properties necessary for producing images of sophisticated multisource data. Multiwavelet fusion scheme can offer more defined features in the fused image than any of the individual source images because of its ability to merge images in multiwavelet space, different frequency are processed differently. The paper is an attempt to combine multisensor images to obtain a single composite image with extended information using multiwavelet fusion scheme. The paper proposes a new fusion algorithm for combining the two source images get better quality image.
