ABSTRACT:
A projective panchromatic sharpening method and apparatus combines registered high spatial resolution panchromatic imagery and lower spatial resolution multispectral imagery to synthesize higher spatial resolution multispectral imagery. The degree of misregistration between bands and the correlation of intensity values are key factors in generating radiometrically accurate and visually crisp output images. The projective panchromatic sharpening method and apparatus comprises two components. The first component determines the linear radiometric relationship between the panchromatic and multispectral bands, and the second component processes pixels to produce the sharpened product.
