Abstract

Satellites often capture multispectral and panchromatic images. The fusion of these two images results into a high resolution pan-sharpened image. In this paper, we apply image encryption scheme on the pan-sharpened four color band image. We fuse the multispectral data with panchromatic data in order to form the high resolution pan-sharpened image. Then this pan-sharpened image is separated into four spectral bands. These bands are encrypted using amplitude-, and phase-truncation approach with different fractional Fourier transform orders.
