Claim One:
1. A method for Pan-sharpening a single panchromatic (Pan) image and a single multispectral (MS) image, comprising: applying a wavelet transform to the Pan image and the MS image to obtain a wavelet transformed Pan image and a wavelet transformed MS image; extracting features, in the form of vectors, from the wavelet transformed Pan image and the wavelet transformed MS image; separating the features into features without missing values and features with missing values; learning a dictionary from features without missing values; predicting the values for the features with the missing values using the dictionary; combining, after the predicting, the features of the low frequency wavelet coefficients and the high frequency coefficients to form a fused wavelet coefficient map; and applying an inverse wavelet transform to the fused wavelet coefficient map to obtain a fused MS image, wherein the steps are performed in a processor.
