Class FeatureSelectN<Point>

All Implemented Interfaces:

public class FeatureSelectN<Point> extends Object implements FeatureSelectLimit<Point>
Selects features periodically in the order they were detected until it hits the limit. This is better than just selecting the first N since features tend to ordered in a very specific way, e.g. top to bottom. you're more likely to get a spread out less biased set this way
