niBlackThreshold
public static void niBlackThreshold(Mat _src, Mat _dst, double maxValue, int type, int blockSize, double k, int binarizationMethod)
Performs thresholding on input images using Niblack's technique or some of the popular variations it inspired. The function transforms a grayscale image to a binary image according to the formulae:- THRESH_BINARY \(dst(x,y) = \fork{\texttt{maxValue}}{if \(src(x,y) > T(x,y)\)}{0}{otherwise}\)
- THRESH_BINARY_INV \(dst(x,y) = \fork{0}{if \(src(x,y) > T(x,y)\)}{\texttt{maxValue}}{otherwise}\) where \(T(x,y)\) is a threshold calculated individually for each pixel.
- Parameters:
_src
- Source 8-bit single-channel image._dst
- Destination image of the same size and the same type as src.maxValue
- Non-zero value assigned to the pixels for which the condition is satisfied, used with the THRESH_BINARY and THRESH_BINARY_INV thresholding types.type
- Thresholding type, see cv::ThresholdTypes.blockSize
- Size of a pixel neighborhood that is used to calculate a threshold value for the pixel: 3, 5, 7, and so on.k
- The user-adjustable parameter used by Niblack and inspired techniques. For Niblack, this is normally a value between 0 and 1 that is multiplied with the standard deviation and subtracted from the mean.binarizationMethod
- Binarization method to use. By default, Niblack's technique is used. Other techniques can be specified, see cv::ximgproc::LocalBinarizationMethods. SEE: threshold, adaptiveThreshold

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

- The number of cols in the window. 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.
