Abstract:
Image fusion integrates the spatial information of
high-resolution panchromatic (PAN) image and the color
information of a low resolution multispectral (MS) image
to produce high resolution MS image. The technique
generates a single new enhanced image that provides
richer information than each of the individual images.
Image fusion can be performed at different levels of
information representation, namely: pixel level, feature
level and decision level. Almost all image fusion
algorithms developed to-date, work only at pixel level.
One of the keys to image fusion algorithms is how
effectively and completely to represent the source
images. The present paper reviews some of the successful
pixel level image fusion algorithms such as principal
component analysis, intensity hue saturation, brovey
transform and multi-scale transform etc., and discusses
their strengths and weaknesses.
Keywords: Pixel –
level image fusion, Principal component analysis,
Intensity hue saturation, Brovey transform, Multiscale
transform.
