Class NonMaxLimiter

java.lang.Object

boofcv.abst.feature.detect.extract.NonMaxLimiter

public class NonMaxLimiter
extends java.lang.Object

Adds the ability to specify the maximum number of points that you wish to return. The selected points will be sorted by feature intensity. If maximums and minimums are found then the total number refers to the total combined number of features. The intensity that it sorts by is the absolute value.

Constructor Detail

NonMaxLimiter

public NonMaxLimiter(NonMaxSuppression nonmax,
                     int maxTotalFeatures)

Configures the limiter

Parameters:

nonmax - Non-maximum suppression algorithm

maxTotalFeatures - The total number of allowed features it can return. Set to a value ≤ 0 to disable.

Method Detail

process

public void process(boofcv.struct.image.GrayF32 intensity)

Extracts local max and/or min from the intensity image. If more than the maximum features are found then only the most intense ones will be returned

Parameters:

intensity - Feature image intensity
