ENVI learning video (Deng Shubin)

ENVI (The Environment for Visualizing Images) is a complete remote sensing image processing platform. The software processing technology in the application collection covers image data input/output, image calibration, image enhancement, correction, orthorectification, mosaic, and data fusion. As well as various transformations, information extraction, image classification, knowledge-based decision tree classification, integration with GIS, DEM and terrain information extraction, radar data processing, and three-dimensional display analysis.
