Method Summary

static void

findEdges(double[] u, double JCRIT, int Q, double[] uE, double[] uNLE, java.util.Vector d, int NE) Given a function u, critical threshold JCRIT, and enhancement exponent Q, and a neighborhood parameter NE, the method returns the edge series uE, the nonlinear enhancement uNLE, a Vector d containing the edge locations.
