| Research Abstract |
This research is concerned with remotely sensed image processing , especially the improvement of spatial resolution for remotely sensed low spatial resolution microwave imagery using high spatial resolution visible images.
MSR (Microwave Scanning Radiometer) image observed by MOS (Marine Observing Satellite)-1 has IFOV size of 23km X 23km. but the resolution of MESSR Images of same satellite has IFOV size of 50m X 50m . In this research, improvement of spatial resolution of MSR image using MESSR images was practiced.
At first, high resolution spatial information extracted from MESSR images by the method of category decomposition. Next, this spatial information carry in MSR image. Then, high spatial resolution MSR image reconstruct with both data by the category composition.
Fig. 1 is a MSR original imagery between southern Hokkaido to northern Aomori in Japan. Figs. 2-4 are reconstructed high spatial MSR images Figs 2-4 are improved spatial resolution 50 times by the presented processing.
