CEDD

public CEDD(double Th0,
            double Th1,
            double Th2,
            double Th3,
            boolean CompactDescriptor)

CEDD

public CEDD()

方法详细资料

extract

public void extract(java.awt.image.BufferedImage image)

从接口复制的说明: Extractor

Extracts the feature vector from a BufferedImage.

指定者:

extract 在接口中 Extractor

参数:

image - the source image

getDistance

public double getDistance(LireFeature vd)

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:

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

返回:

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

getByteHistogram

public byte[] getByteHistogram()

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:

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:

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.

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
