Constructor & Destructor Documentation

__init__() [1/4]

None eVision.EImageStatisticsC24.__init__

(

self

)

Constructs an eVision.EImageStatisticsC24 object.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this constructor will have an influence on the behavior of this class.

__init__() [2/4]

None eVision.EImageStatisticsC24.__init__	(		self,
		eVision.EImageStatisticsC24	other )

Constructs an eVision.EImageStatisticsC24 object.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this constructor will have an influence on the behavior of this class.

Parameters

other

The other instance of eVision.EImageStatisticsC24 from which to construct this one.

__init__() [3/4]

None eVision.EImageStatisticsC24.__init__	(		self,
		eVision.EROIC24 | None	image,
		eVision.ERegion | None	region )

Constructs an eVision.EImageStatisticsC24 object.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this constructor will have an influence on the behavior of this class.

Parameters

image	Reference to the image on which statistics are computed.
region	Reference to the region used to delimit the image.

__init__() [4/4]

None eVision.EImageStatisticsC24.__init__	(		self,
		eVision.EROIC24 | None	image )

Constructs an eVision.EImageStatisticsC24 object.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this constructor will have an influence on the behavior of this class.

Parameters

image

Reference to the image on which statistics are computed.

Member Function Documentation

PixelAverage()

list[float] eVision.EImageStatisticsC24.PixelAverage

(

self

)

Computes the pixel average on each of the 3 channels of the image (and region) set by eVision.EImageStatisticsC24.SetImage.

Remarks:

Computes average if average wasn't computed previously.

PixelStdDev()

list[float] eVision.EImageStatisticsC24.PixelStdDev

(

self

)

Computes the standard deviations and correlations of the channels of the pixels on the image (and region) set by eVision.EImageStatisticsC24.SetImage.

Returns a vector containing:

• [0] standard deviation of the 1st channel
• [1] standard deviation of the 2nd channel
• [2] standard deviation of the 3rd channel
• [3] correlation between the 1st and 2nd channel
• [4] correlation between the 2st and 3rd channel
• [5] correlation between the 3rd and 1st channel

Remarks:

Computes the averages, standard derivations and variances if the standard derivations weren't computed previously.

PixelVariances()

list[float] eVision.EImageStatisticsC24.PixelVariances

(

self

)

Computes the variances and covariances of the channels of the pixels on the image (and region) set by eVision.EImageStatisticsC24.SetImage.

Returns a vector containing:

• [0] variance of the 1st channel
• [1] variance of the 2nd channel
• [2] variance of the 3rd channel
• [3] covariance between the 1st and 2nd channel
• [4] covariance between the 2st and 3rd channel
• [5] covariance between the 3rd and 1st channel

Remarks:

Computes the averages, standard derivation and variances if the variances weren't computed previously.

SetImage() [1/2]

None eVision.EImageStatisticsC24.SetImage	(		self,
		eVision.EROIC24 | None	image )

Sets the reference to the image on which the statistics will be computed.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this method will have an influence on the behavior of this class.

Parameters

image

Reference to the image on which statistics are computed.

SetImage() [2/2]

None eVision.EImageStatisticsC24.SetImage	(		self,
		eVision.EROIC24 | None	image,
		eVision.ERegion | None	region )

Sets the reference to the image on which the statistics will be computed.

Remarks:

Image and region aren't copied inside the class. Consequently, modifying them after calling this method will have an influence on the behavior of this class.

Parameters

image	Reference to the image on which statistics are computed.
region	Reference to the region used to delimit the image.
