RGB Components Constructed from Three Bands of Multispectral Images through IHS Transformation

By applying the IHS transformation to RGB components formed from three bands of multispectral images, the spatial features (I) and spectral features (H and S) of the image can be separated. This technique enables independent manipulation of image brightness and color information, which is particularly useful in applications like remote sensing, image fusion, and color enhancement.
