IMAGE FUSION AND IMAGE QUALITY ASSESSMENT OF FUSED IMAGES
It is of great value to fuse a high-resolution panchromatic image and low-resolution multi-spectral images for object recognition. In the paper, tow frames of remotely sensed imagery, including ZY03 and SPOT05, are selected as the source data. Four fusion methods, including Brovey, PCA, Pansharp, an...

| Summary: | It is of great value to fuse a high-resolution panchromatic image and low-resolution multi-spectral images for object recognition. In the
paper, tow frames of remotely sensed imagery, including ZY03 and SPOT05, are selected as the source data. Four fusion methods,
including Brovey, PCA, Pansharp, and SFIM, are used to fuse the images of multispectral bands and panchromatic band. Three
quantitative indicators were calculated and analyzed, that is, gradient, correlation coefficient and deviation. According to
comprehensive evaluation and comparison, the best effect is SFIM transformation, combined with fusion image through four
transformation methods. |
