CovarianceEstimation(InputArray, OutputArray, int, int)

Computes the estimated covariance matrix of an image using the sliding window forumlation.

public static void CovarianceEstimation(InputArray src, OutputArray dst, int windowRows, int windowCols)

Parameters

src InputArray

The source image. Input image must be of a complex type.

dst OutputArray

The destination estimated covariance matrix. Output matrix will be size (windowRowswindowCols, windowRowswindowCols).

windowRows int

The number of rows in the window.

windowCols int

The number of cols in the window.

Remarks

The window size parameters control the accuracy of the estimation. The sliding window moves over the entire image from the top-left corner to the bottom right corner.Each location of the window represents a sample. If the window is the size of the image, then this gives the exact covariance matrix. For all other cases, the sizes of the window will impact the number of samples and the number of elements in the estimated covariance matrix.
