Parameters

sourceImage

Pointer to the source image/ROI.

standardDeviation

Reference to a variable in which the standard deviation of the pixel values is to be stored (for gray-level images).

mean

Reference to a variable in which the average value of the pixels is to be stored (for gray-level images).

standardDeviation0

Reference to a variable in which the standard deviation of the values of the first color component is to be stored (for color images).

standardDeviation1

Reference to a variable in which the standard deviation of the values of the second color component is to be stored (for color images).

standardDeviation2

Reference to a variable in which the standard deviation of the values of the third color component is to be stored (for color images).

correlation01

Reference to a variable in which the correlation between the values of the first color component and the second color component is to be stored (for color images).

correlation12

Reference to a variable in which the correlation between the values of the second color component and the third color component is to be stored (for color images).

correlation20

mean0

Reference to a variable in which the average value of the first color component is to be stored (for color images).

mean1

Reference to a variable in which the average value of the second color component is to be stored (for color images).

mean2

Reference to a variable in which the average value of the third color component is to be stored (for color images).

region

Pointer to a region to apply the function only on a particular region in the image.

mask

Pointer to a mask to apply the function only on a particular region in the image. Note: the mask must have the same size as the source image.

Remarks

The variance can be obtained from the standard deviation by squaring it.
