The application of hyperspectral remote sensing has been a research focus in recent years, and one of its fundamental goals is to detect and classify the constituent materials for each pixel in the scene, which is pixel unmixing. This research proposes spectral reconstruction, which is the inverse process of pixel unmixing. It can be used to analyze the essence of the hyperspectral imaging procedure...
With the advantage of acquiring spatial information and more spectral information, Hyperspectral imager is widely applied in the fields of earth-observation, precision agriculture, etc. In order to improve the quantitative ability of hyperspectral imagery, accurate radiometric and spectral calibrations are necessary. Shifts in channel center wavelengths and changes in spectral resolution may occur...
For the restriction of the air, sensor and kinds of natural conditions, satellites can't get enough remote sensing data to meet the needs of scientific research, especially for the western mountainous area. This study reconstructed the TM images of Guizhou mountainous areas to achieve their hyperspectral images based on UPDM analysis, and classified the hyperspectral images for vegetation information...
