Resolution enhancement RE methods are not based on wavelets and it suffer from the disadvantage of losing high frequency content which results in blurring. The discrete wavelet-transform-based (DWT) RE scheme forms artifacts which are because of a DWT shift-variant property. The dual-tree complex wavelet transform (DT-CWT) and Adaptive Bilateral Filter (ABF) are based on a wavelet-domain approach and it proposed for satellite images of RE. DT-CWT is nearly shift invariant and it is decomposed from a satellite input image which is used to obtain high frequency sub-bands. Lanczos interpolator used for low-resolution input images and the high-frequency sub-bands interpolation and the high frequency sub-bands are approved through an ABF filter to provide for the artifacts generated by DT-CWT. The filtered high-frequency sub-bands as well as the LR input image are combined using inverse DT-CWT to get a resolution-enhanced image. Objective and subjective analyses make known the advantage of the planned technique over the conventional with state-of-the-art RE techniques.
