List<KeyValuePair<int, float> > Histogram.findCluster

(

float[]

hist

)

Finds all clusters in the given histogram.

Parameters

[in]

hist

The histogram to look for clusters.

Returns

Return_Description A list of KeyValuePairs, which contains the center indices and the size of all found clusters.

Finds all clusters of the given histogram, i.e. the center indices and sizes of all areas, which contain no values which are 0.

List<KeyValuePair<int, float> > Histogram.findMax

(

float[]

hist

)

Finds all local maxima in the given histogram.

Parameters

[in]

hist

The histogram to look for maxima.

Returns

Return_Description A list of KeyValuePairs, which contains the indices and the values of all found local maxima.

Finds all values which are larger than or equals their direct neighbors in the given histogram.

List<KeyValuePair<int, float> > Histogram.findMin

(

float[]

hist

)

Finds all local minima in the given histogram.

Parameters

[in]

hist

The histogram to look for minima.

Returns

Return_Description A list of KeyValuePairs, which contains the indices and the values of all found local minima.

Finds all values which are smaller as or equals their direct neighbors in the given histogram.

Definition at line 84 of file Histogram.cs.

int [] Histogram.findSimilarArea	(	int	index,
		float	eps,
		float[]	hist
	)

Finds all surrounding Values, which are not larger than the value with the given index by eps in the given histogram.

Parameters

[in]	index	The index, where to look for similar values.
[in]	eps	The value, by which similar values can be larger than the value with the given index.
[in]	hist	The histogram, where to look for similar values.

Returns

Return_Description

Finds all surrounding Values, which are not larger than the value with the given index by eps in the given histogram.
