Hyperspectral Image Analysis using ENVI (ENvironment for Visualizing Images)

摘要

Hyperspectral imaging is a relatively new technology which draws much attention from the scientists now. With information provided on hundreds of narrow and continuous bands, it finds applications in many areas such as mineral identification, environmental monitoring, agricultural survey, medical examination. However, it is not an easy task to utilize the hyperspectral images, due to the large data volume. Certain tools are needed to analyze the hyperspectral image. As an example, the ENvironment for Visualizing Images (ENVI) software is used for the study of a sample hyperspectral image.
