The Application of Digital Image Merging in the Color Aero-photography with Black-and-White Film and Tricolor Grating

摘要

In this paper, digital image merging method is used to the color aero-photography with black-white film and tricolor grating. During the digital decoding processing, we merging the high spatial resolution panchromatic image decoded from the zero order frequency spectrum into the low spatial resolution multispectral image decoded from the first order frequency spectrums to improve the quality of the decoded color image.
