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

extractor - Feature extraction algorithm.

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

Returns:

General feature detector

nonmax

public static NonMaxSuppression nonmax(ConfigExtract config)

Standard non-max feature extractor.

Parameters:

config - Configuration for extractor

Returns:

A feature extractor.

nonmaxCandidate

public static NonMaxSuppression nonmaxCandidate(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(ConfigExtract config,
                                          int maxFeatures)

Creates a non-maximum limiter using the specified configuration

Parameters:

config - non-maxumum settings

maxFeatures - maximum allowed features

Returns:

The NonMaxLimiter
