A new technique is developed for the data fusion of two images.Two spatially registered images with differing spatial resolutions and color content are merged by modifying the spectral intensity component and then reconstructing the fusion image by means of the inverse IHS transform.The intensity component is modified by a best transform curve
which is obtained by evolutionary strategies
and is closer to the intensity component of multispectral image and is closer to the high resolution image in the meantime.Experimental comparisons show that the method proposed in this paper performs better in preserving spatial resolutions and color content than that of traditional IHS transform technique and wavelet transform fusion method.
