Syntax

public static class ContentAlgorithms

Methods

CreateBroadbandTemplate1(TemplateManifest, Dictionary<String, Double[,]>)

This algorithm is used for broad band events such as a bird chorus. It selects acoustic content over a band of several kHz and calculates a content score based on a template match to what is in the band.

Declaration

public static Dictionary<string, double[]> CreateBroadbandTemplate1(TemplateManifest manifest, Dictionary<string, double[, ]> templateIndices)

Parameters

Type	Name	Description
TemplateManifest	manifest	A previously prepared template.
Dictionary<String, Double[,]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Dictionary<String, Double[]>	A similarity score.

CreateFullBandTemplate1(TemplateManifest, Dictionary<String, Double[,]>)

This algorithm is used for full band width events such as a rain and wind. It calculates a content score based on a template match to what is in the full spectrum.

Declaration

public static Dictionary<string, double[]> CreateFullBandTemplate1(TemplateManifest manifest, Dictionary<string, double[, ]> templateIndices)

Parameters

Type	Name	Description
TemplateManifest	manifest	A description of the template which is to be created.
Dictionary<String, Double[,]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Dictionary<String, Double[]>	A new template.

CreateNarrowBandTemplate1(TemplateManifest, Dictionary<String, Double[,]>)

This algorithm is used for narrow band events such as an insect bird chorus or content due to narrow band calls of a single bird species. It searches the full spectrum for a match to the template and then calculates how much of the match weight is in the correct narrow freq band.

Declaration

public static Dictionary<string, double[]> CreateNarrowBandTemplate1(TemplateManifest manifest, Dictionary<string, double[, ]> templateIndices)

Parameters

Type	Name	Description
TemplateManifest	manifest	A previously prepared template.
Dictionary<String, Double[,]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Dictionary<String, Double[]>	A similarity score.

GetBroadbandContent1(Dictionary<String, Double[]>, TemplateManifest, Dictionary<String, Double[]>)

This algorithm is used for broad band events such as a bird chorus. It selects acoustic content over a band of several kHz and calculates a content score based on a template match to what is in the band.

Declaration

public static double GetBroadbandContent1(Dictionary<string, double[]> oneMinuteOfIndices, TemplateManifest template, Dictionary<string, double[]> templateIndices)

Parameters

Type	Name	Description
Dictionary<String, Double[]>	oneMinuteOfIndices	Derived from the source recording.
TemplateManifest	template	A previously prepared template.
Dictionary<String, Double[]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Double	A similarity score.

GetFullBandContent1(Dictionary<String, Double[]>, TemplateManifest, Dictionary<String, Double[]>)

This algorithm is used for full band width events such as a rain and wind. It calculates a content score based on a template match to what is in the full spectrum.

Declaration

public static double GetFullBandContent1(Dictionary<string, double[]> oneMinuteOfIndices, TemplateManifest template, Dictionary<string, double[]> templateIndices)

Parameters

Type	Name	Description
Dictionary<String, Double[]>	oneMinuteOfIndices	Derived from the source recording.
TemplateManifest	template	A previously prepared template.
Dictionary<String, Double[]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Double	A similarity score.

GetNarrowBandContent1(Dictionary<String, Double[]>, TemplateManifest, Dictionary<String, Double[]>)

This algorithm is used for narrow band events such as an insect bird chorus or content due to narrow band calls of a single bird species. It searches the full spectrum for a match to the template and then calculates how much of the match weight is in the correct narrow freq band.

Declaration

public static double GetNarrowBandContent1(Dictionary<string, double[]> oneMinuteOfIndices, TemplateManifest template, Dictionary<string, double[]> templateIndices)

Parameters

Type	Name	Description
Dictionary<String, Double[]>	oneMinuteOfIndices	Derived from the source recording.
TemplateManifest	template	A previously prepared template.
Dictionary<String, Double[]>	templateIndices	The actual dictionary of template arrays.

Returns

Type	Description
Double	A similarity score.
