The resulting image will be more informative than any of the input images. Image fusion of Multispectral image and panchromatic image is called as Pan-sharpening. Pan-sharpening combines a low-resolution color multispectral image with a high-resolution grayscale panchromatic image to create a high-resolution fused color image. "Pan Sharpening" is shorthand for "Panchromatic (PAN) sharpening". It means using a panchromatic (single band) image to "sharpen" a multispectral image. In this sense, to "sharpen" means to increase the spatial resolution of a multispectral image. A multispectral image contains a higher degree of spectral resolution than a panchromatic image, while often a panchromatic image will have a higher spatial resolution than a multispectral image. The Intensity-Hue-Saturation (IHS) method is a popular pan-sharpening method used for its efficiency and high spatial resolution. However, the final image produced experiences spectral distortion (Color distortion). In this paper, we introduce IHS methods with modifications to improve the spectral quality of the image. This paper explains the IHS, GIHS, AIHS and EAIHS methods for quality fusion techniques. The quality of the fusion will be decided by the parameters CC, RMSE, RASE, ERGAS,SAM, UIQI and SC.
Visual Cryptography for Gray Image

A distinctive property of VCS is that one can visually decode the secret image by superimposing shares without computation. Here we are applying Visual Cryptography Scheme (VCS) on gray image instead of binary image. So, generated shares are gray share, not binary shares that are generated by the binary image. We present an approach for embedding visual cryptographically generated gray image shares in the host images to provide authentication for the VC shares and makes these secret shares invisible by embedding them into host images. The secret shares generated from VC encryption are watermarked into some host images using digital watermarking. To provide double security of image shares digital watermarking is used. Thus secret shares are not available for any alteration by the adversaries who try to create fake shares. The scheme is more secure. The effective and secure...
