The objectives of this work are 1) to register individual bands in a multispectral image, 2) register multispectral images with areas of overlap, and 3) construct a mosaic of a set of images to construct a map of an area.
Following images are from ADAR Scanner System 5500 provided by Positive Systems. Only Red, Green, and Blue bands are shown below.
Fig. 1. Individual red, green, blue bands and combined color image of an urban area.
Fig. 2. Green and blue bands resampled by linear transformation functions to register with the red band. Color image obtained by combining red, resampled green, and resampled blue bands.
Fig. 3. Green and blue bands resampled by locally adaptive transformation functions. Combined red, resampled green, and resampled blue bands.
Fig. 4. Images obtained by sharpening the color image of Fig. 3 by inverse filtering.
