Principles of Remote Sensing - Centre for Remote Imaging ...

Image Processing and Analysis. Many image processing and analysis techniques have been developed to aid the interpretation of remote sensing images and to extract as much information as possible from the images. The choice of specific techniques or algorithms to use depends on the goals of each individual project.
