```
    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.
    
    The threshold value $T(x, y)$ is determined based on the binarization method chosen. For classic Niblack, it is the mean minus $ k $ times standard deviation of $\texttt{blockSize} \times\texttt{blockSize}$ neighborhood of $(x, y)$. The function can't process the image in-place.
    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.
    
    r - The user-adjustable parameter used by Sauvola's technique. This is the dynamic range of standard deviation. SEE: threshold, adaptiveThreshold

    Parameters:
    
    src - Source 8-bit or floating-point, 1-channel or 3-channel image.
    
    dst - Destination image of the same size and type as src.
    
    d - Diameter of each pixel neighborhood that is used during filtering. If it is non-positive, it is computed from sigmaSpace .
    
    sigmaColor - Filter sigma in the color space. A larger value of the parameter means that farther colors within the pixel neighborhood (see sigmaSpace ) will be mixed together, resulting in larger areas of semi-equal color.
    
    sigmaSpace - Filter sigma in the coordinate space. A larger value of the parameter means that farther pixels will influence each other as long as their colors are close enough (see sigmaColor ). When d>0 , it specifies the neighborhood size regardless of sigmaSpace . Otherwise, d is proportional to sigmaSpace . Note: rollingGuidanceFilter uses jointBilateralFilter as the edge-preserving filter. SEE: jointBilateralFilter, bilateralFilter, amFilter

    src - source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.

    dst - destination image. For more details about the Fast Bilateral Solver parameters, see the original paper CITE: BarronPoole2016. Note: Confidence images with CV_8U depth are expected to in [0, 255] and CV_32F in [0, 1] range.

```
    Factory method, create instance of FastGlobalSmootherFilter and execute the initialization routines.
    
    Parameters:
    
    guide - image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.
    
    lambda - parameter defining the amount of regularization
    
    sigma_color - parameter, that is similar to color space sigma in bilateralFilter.
    
    lambda_attenuation - internal parameter, defining how much lambda decreases after each iteration. Normally, it should be 0.25. Setting it to 1.0 may lead to streaking artifacts.
    
    num_iter - number of iterations used for filtering, 3 is usually enough. For more details about Fast Global Smoother parameters, see the original paper CITE: Min2014. However, please note that there are several differences. Lambda attenuation described in the paper is implemented a bit differently so do not expect the results to be identical to those from the paper; sigma_color values from the paper should be multiplied by 255.0 to achieve the same effect. Also, in case of image filtering where source and guide image are the same, authors propose to dynamically update the guide image after each iteration. To maximize the performance this feature was not implemented here.

```
    Computes the estimated covariance matrix of an image using the sliding window forumlation.
    
    Parameters:
    
    src - The source image. Input image must be of a complex type.
    
    dst - The destination estimated covariance matrix. Output matrix will be size (windowRows*windowCols, windowRows*windowCols).
    
    windowRows - The number of rows in the window.
    
    windowCols - 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.

```
    Initializes a SuperpixelSEEDS object.
    
    Parameters:
    
    image_width - Image width.
    
    image_height - Image height.
    
    image_channels - Number of channels of the image.
    
    num_superpixels - Desired number of superpixels. Note that the actual number may be smaller due to restrictions (depending on the image size and num_levels). Use getNumberOfSuperpixels() to get the actual number.
    
    num_levels - Number of block levels. The more levels, the more accurate is the segmentation, but needs more memory and CPU time.
    
    prior - enable 3x3 shape smoothing term if >0. A larger value leads to smoother shapes. prior must be in the range [0, 5].
    
    histogram_bins - Number of histogram bins.
    
    double_step - If true, iterate each block level twice for higher accuracy. The function initializes a SuperpixelSEEDS object for the input image. It stores the parameters of the image: image_width, image_height and image_channels. It also sets the parameters of the SEEDS superpixel algorithm, which are: num_superpixels, num_levels, use_prior, histogram_bins and double_step. The number of levels in num_levels defines the amount of block levels that the algorithm use in the optimization. The initialization is a grid, in which the superpixels are equally distributed through the width and the height of the image. The larger blocks correspond to the superpixel size, and the levels with smaller blocks are formed by dividing the larger blocks into 2 x 2 blocks of pixels, recursively until the smaller block level. An example of initialization of 4 block levels is illustrated in the following figure. ![image](pics/superpixels_blocks.png)
