Detailed Description

template<class T>
class w2img::VQSectorization< T >

Given a set of spatial grids representing various observed quantities, divides the spatial grid into sectors using vector quantization.

The sectors represent areas where the data are similar.

Works with RadialSet and LatLonGrid

The data have to be scaled in the range 0-1.

Pixels that are missing from *any* field will not be used. If you don't want this behavior, replace MissingData with 0 or something.
