An Efficient Algorithm for Satellite Images Fusion based on Contourlet Transform

摘要: This paper proposes a new fusion method for multiespectral (MULTI) and panchromatic (PAN) images that uses highly anisotropic redundant representation of images. methodology join the simplicity Wavelet transform, calculated using trous algorithm, with benefits multidirectional transforms like Contourlet Transform. That has permitted an adequate extraction information from source images, in order to obtain fused high spatial spectral quality simultaneously. The been implemented through directional low pass filter bank computational complexity. correspond those captured by IKONOS satellite (panchromatic multispectral). influence parameters global investigated. results obtained indicate proposed provides objective control trade-off determination appropriate set parameters.
