摘要：

The use of cubic spline wavelets for merging high spatial content of panchromatic (PAN) data and spectral contents of multispectral (LISS-3) data of IRS-1C/1D spacecraft is proposed here. It is shown that the: proposed method preserves the spatial content of the original PAN data and the spectral content of the LISS-3 better than many of the conventional approaches. It is also suggested that the spatial content of the merged data can further be enhanced by first correcting the PAN data for overall modulation transfer function (MTF) of the sensor. The overall MTF was realized with a piecewise linear model and using the sensor specified MTF at nyquist frequency.
