Guided Filter and IHS-Based Pan-Sharpening
Amina Jameel, Muhammad Mohsin Riaz, Abdul Ghafoor · IEEE Sensors Journal · 2015
A guided filter and intensity-hue-saturation-based pan-sharpening scheme is proposed. The scheme combines the high-resolution unispectral and low-resolution multispectral images considering the intensity levels and the spatial information. Guided filtering is used to further refine the weight maps for each pixel. The simulation results show that the suggested scheme mostly yields superior results compared with the existing schemes.
