Image fusion is a process to obtain new images containing more information by combining images obtained same or different sensors. With most of the earth observation satellites, high spatial resolution panchromatic images and low spatial resolution multispectral images are obtained. As an example of image fusion “pan sharpening” is a process of combining of high spatial resolution panchromatic images...
Many image fusion techniques have been proposed so as to achieve optimal resolution in the spatial and spectral domains. The Beijing-1 Micro-Satellite images have their own unique characteristics. The resolution ratio of its multi-spectral image to panchromatic image exceeds 4:1. It is often a challenge to pan-sharpen images with such a high spatial resolution ratio. In this paper, our study is to...
The fusion of multi-source remote sensing images can utilize the multi-source information and obtain richer and more objective information compared with the single source image data. ALOS is a new source of high-resolution satellite data, hence research on the practical methods for ALOS data fusion has great significance in prompting the ALOS data application. Based on the features of ALOS data, some...
