Abstract :
Pan-sharpened is an image fusion technique, which is designed to increase the resolution of multispectral (MS) images using panchromatic (Pan) image. In this paper, we evaluate fusion techniques for Pan-sharpened THEOS (THailand Earth Observation System) images. A calibrated THEOS imagery with heterogeneous land cover types was evaluated by different fusion techniques. This paper studied both intensity-hue-saturation (IHS) transformation and multiresolution analysis (MRA) to evaluate and improve the sharpening performance. The fusion results were visually and objectively evaluated.
