SurfFeature

public SurfFeature(com.stromberglabs.jopensurf.SURFInterestPoint surfInterestPoint)

SurfFeature

public SurfFeature()

方法详细资料

getDistance

public double getDistance(LireFeature f)

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:

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

返回:

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

getByteArrayRepresentation

public byte[] getByteArrayRepresentation()

Provides a much faster way of serialization.

指定者:

getByteArrayRepresentation 在接口中 LireFeature

返回:

a byte array that can be read with the corresponding method.

另请参阅:

CEDD.setByteArrayRepresentation(byte[])

setByteArrayRepresentation

public void setByteArrayRepresentation(byte[] in)

Reads descriptor from a byte array. Much faster than the String based method.

指定者:

setByteArrayRepresentation 在接口中 LireFeature

参数:

in - byte array from corresponding method

另请参阅:

CEDD.getByteArrayRepresentation()

setByteArrayRepresentation

public void setByteArrayRepresentation(byte[] in,
                                       int offset,
                                       int length)

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:

in - the byte[] array containing the data.

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

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

另请参阅:

LireFeature.getByteArrayRepresentation()

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.

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.

getX

public double getX()

指定者:

getX 在接口中 LocalFeature

getY

public double getY()

指定者:

getY 在接口中 LocalFeature

getSize

public double getSize()

指定者:

getSize 在接口中 LocalFeature

getClassOfExtractor

public java.lang.Class<?> getClassOfExtractor()

指定者:

getClassOfExtractor 在接口中 LocalFeature
