Method	Description
Measure ( double convolution ) : int[]	Calculates the chamfer from a convolution
NormalizedSimilarity ( int chamfer1, int chamfer2 ) : double
ScaleChamfer ( int input, int size ) : int[]
ScanSimilarity ( int chamfer1, int chamfer2 ) : double[]	Scan Similarity calculates the similarity for possible alignments of two chamfers such that the smaller edge is always bound by the larger edge
Similarity ( int smaller, int larger, int start ) : double	Calculates how similar two chamfers are 'i.e' opposite of the chamfer distance Does so by taking the dot product of the two chamfer vectors normalized by the max( dot product of either of the chamfers).
Sparsity ( int chamfer ) : long	Indicates the sparsity of the chamfer by sum(integrating) the chamfer vector

Method Details

Measure() public static method

Calculates the chamfer from a convolution

public static Measure ( double convolution ) : int[]
convolution	double	An array of doubles, where 0 indicates no feature and non zero indicates a feature
return	int[]

NormalizedSimilarity() public static method

public static NormalizedSimilarity ( int chamfer1, int chamfer2 ) : double
chamfer1	int
chamfer2	int
return	double

ScaleChamfer() public static method

public static ScaleChamfer ( int input, int size ) : int[]
input	int
size	int
return	int[]

ScanSimilarity() public static method

Scan Similarity calculates the similarity for possible alignments of two chamfers such that the smaller edge is always bound by the larger edge

public static ScanSimilarity ( int chamfer1, int chamfer2 ) : double[]
chamfer1	int	Chamfer vector
chamfer2	int	Other shreds Chamfer vector
return	double[]

Similarity() public static method

Calculates how similar two chamfers are 'i.e' opposite of the chamfer distance Does so by taking the dot product of the two chamfer vectors normalized by the max( dot product of either of the chamfers).

public static Similarity ( int smaller, int larger, int start ) : double
smaller	int	Smaller Chamfer Vector
larger	int	Larger Chamfer vector
start	int	Starting offset
return	double

Sparsity() public static method

Indicates the sparsity of the chamfer by sum(integrating) the chamfer vector

public static Sparsity ( int chamfer ) : long
chamfer	int	chamfer vector
return	long
