This service performs a Brovey transformation on three multispectral and a panchromatic satellite image channels to merge multispectral and high-resolution panchromatic channels.
The objective of image fusion is to combine information from multiple images of the same scene. The result of image fusion is a new image which is more suitable for human and machine perception or further image processing tasks such as segmentation, feature extraction and object recognition [Gonzalo Pajares et al., 2004].
Operation:
fusion_brovey - Uses GRASS command i.fusion.brovey to perform a Brovey transformation using three multispectral and the panchromatic satellite image scene channels, then combine the three RGB output maps with r.composite to a single one.
