Usage

From source file:gdsc.smlm.model.UniformDistribution.java

/**
 * Create a new uniform distribution using a Halton sequence
 * /*  ww w .j a v  a 2  s .  com*/
 * @param min
 *            The minimum bounds for the distribution
 * @param max
 *            The maximum bounds for the distribution
 * @param seed
 *            Start at the i-th point in the Halton sequence
 */
public UniformDistribution(double[] min, double[] max, int seed) {
    //HaltonSequenceGenerator randomVectorGenerator = new HaltonSequenceGenerator(3);
    // The Halton sequence based on the prime of 2 does not provide great variety in the
    // lesser significant digits when simulating a 512x512 pixel image. This is not suitable for
    // PSF fitting since we require variation to at least 3 decimal places.
    HaltonSequenceGenerator randomVectorGenerator = new HaltonSequenceGenerator(3, new int[] { 3, 5, 7 }, null);
    randomVectorGenerator.skipTo(Math.abs(seed));
    init(min, max, randomVectorGenerator);
