类 ShapemeHistogram

java.lang.Object

net.semanticmetadata.lire.imageanalysis.features.local.shapecontext.ShapemeHistogram

所有已实现的接口:

FeatureVector, LireFeature, LocalFeature

public class ShapemeHistogram
extends java.lang.Object
implements LocalFeature

Created by Lukas Knoch on 23.09.15. This class contains the histogram representation of the ShapeContext feature. It is actually a global feature aggregated by many local features, but needs to be a local feature as that is required by the current indexer and searcher configuration.

ShapemeHistogram

public ShapemeHistogram()

方法详细资料

getFeatureName

public java.lang.String getFeatureName()

从接口复制的说明: LireFeature

Gives a descriptive name of the feature, i.e. a name to show up in benchmarks, menus, UIs, etc.

指定者:

getFeatureName 在接口中 LireFeature

返回:

the name of the feature.

getFieldName

public java.lang.String getFieldName()

从接口复制的说明: LireFeature

Returns the preferred field name for indexing.

指定者:

getFieldName 在接口中 LireFeature

返回:

the field name preferred for indexing in a Lucene index.

getByteArrayRepresentation

public byte[] getByteArrayRepresentation()

从接口复制的说明: LireFeature

Returns a compact byte[] based representation of the feature vector.

指定者:

getByteArrayRepresentation 在接口中 LireFeature

返回:

a compact byte[] array containing the feature vector.

另请参阅:

LireFeature.setByteArrayRepresentation(byte[])

setByteArrayRepresentation

public void setByteArrayRepresentation(byte[] bytes)

从接口复制的说明: LireFeature

Sets the feature vector values based on the byte[] data. Use LireFeature.getByteArrayRepresentation() to generate a compatible byte[] array.

指定者:

setByteArrayRepresentation 在接口中 LireFeature

参数:

bytes - the byte[] data.

另请参阅:

LireFeature.getByteArrayRepresentation()

setByteArrayRepresentation

public void setByteArrayRepresentation(byte[] bytes,
                                       int i,
                                       int i1)

从接口复制的说明: LireFeature

Sets the feature vector values based on the byte[] data. Use LireFeature.getByteArrayRepresentation() to generate a compatible byte[] array.

指定者:

setByteArrayRepresentation 在接口中 LireFeature

参数:

bytes - the byte[] array containing the data.

i - the offset, i.e. where the feature vector starts.

i1 - the length of the data representing the feature vector.

另请参阅:

LireFeature.getByteArrayRepresentation()

getDistance

public double getDistance(LireFeature lireFeature)

从接口复制的说明: LireFeature

The distance function for this type of feature

指定者:

getDistance 在接口中 LireFeature

参数:

lireFeature - the feature vector to compare the current instance to.

返回:

the distance (or dissimilarity) between the instance and the parameter.

getFeatureVector

public double[] getFeatureVector()

从接口复制的说明: FeatureVector

Convenience method to get the feature vector as double[] array. This method is used by classifiers, etc.

指定者:

getFeatureVector 在接口中 FeatureVector

返回:

the feature vector as a double[] array.

getX

public double getX()

指定者:

getX 在接口中 LocalFeature

getY
