public interface FeatureVector

This interface represents a feature vector as used for Content-Based Retrieval (CBR). It defines methods for computing a measure of similarity between feature vectors that must be implemented by feature vector classes.

Method Summary

float

distance(FeatureVector v) This method computes the distance between this vector and the given one.

Method Detail

distance

public float distance(FeatureVector v)

This method computes the distance between this vector and the given one. The distance is represented by a value in the range [0.0,1.0]. A value of 0 means both vectors are identical. A value of 1.0 denotes infinite distance.

Parameters:

v - The feature vector to compare to.

Returns:

The measure of similarity between this and the given feature vector.
