Method Details

general

public static <I extends ImageGray<I>,
D extends ImageGray<D>>
GeneralFeatureDetector<I,D> general(GeneralFeatureIntensity<I,D> intensity,
 @Nullable
 @Nullable NonMaxSuppression extractorMin,
 @Nullable
 @Nullable NonMaxSuppression extractorMax,
 FeatureSelectLimitIntensity<Point2D_I16> selector,
 int maxFeatures)

Creates a generalized feature detector/extractor that adds n-best capability to NonMaxSuppression and performs other house keeping tasks. Handles calling GeneralFeatureIntensity itself.

Parameters:

intensity - Feature intensity algorithm

extractorMin - Feature extraction algorithm for local minimums

extractorMax - Feature extraction algorithm for local maximums

selector - Selects features when there is more than the maximum allowed

maxFeatures - Maximum number of features it should return. -1 to return them all.

Returns:

General feature detector

nonmax

public static NonMaxSuppression nonmax(@Nullable
 @Nullable ConfigExtract config)

Standard non-max feature extractor.

Parameters:

config - Configuration for extractor

Returns:

A feature extractor.

nonmaxCandidate

public static NonMaxSuppression nonmaxCandidate(@Nullable
 @Nullable ConfigExtract config)

Non-max feature extractor which saves a candidate list of all the found local maximums..

Parameters:

config - Configuration for extractor

Returns:

A feature extractor.

nonmaxLimiter

public static NonMaxLimiter nonmaxLimiter(@Nullable
 @Nullable ConfigExtract configExtract,
 ConfigSelectLimit configSelect,
 int maxFeatures)

Creates a non-maximum limiter using the specified configuration

Parameters:

configExtract - non-maxumum settings

maxFeatures - maximum allowed features

Returns:

The NonMaxLimiter
