HSV, IHS and PCA Based Image Fusion: A Review

Many remote-sensing satellites can obtain images in multispectral and panchromatic bands. By fusing lowresolution multispectral and high-resolution panchromatic images, one can obtain high-resolution multispectral images. The objective is to obtain more information from the fused image than from the individual images. This paper provides an overview of the color transform based techniques available in the literature for the fusion of multispectral and panchromatic images. The evaluation of the fusion technique employed is performed using various quality metrics, to compare and assess the fusion technique employed.
