Supervised Classifica tion Part 1

Land cover classification of remote sensing imagery is a task which falls into

the general category of pattern recognition. Pattern recognition problems, in

turn, are usually approached by developing appropriate machine learning al-

gorithms. Broadly speaking, machine learning involves tasks for which there

is no known dire ct method to compute a desired output from a set of inputs.

The strategy a dopted is for the computer to “ learn” from a set of representa-

tive e xamples.

In the case of supervised classification, the task can often be seen as one

of modeling probability distributions. On the basis of representativ ...
