Digital Image Processing

Remotely sensed digital images can be studied by qualitative and quantitative analyses for the extraction of information.

These two processing procedures have considerable differences, related, firstly, to the human mind’s logical mechanisms and, secondly, to computing systems’ important contribution. The qualitative analysis is related to human interpretation skills (visual interpretation or photo interpretation), the quantitative one to the automatic (digital processing), or semi-automatic interpretation (if there are controls by the operator in one or more phases of the processing).
