+
+    :param dst: Destination image of the same size and type as  ``src`` .
+
+    :param ksize: filter kernel size.
+
+    :param sigmaSpace: Filter sigma in the coordinate space. It has similar meaning with ``sigmaSpace`` in ``bilateralFilter``.
+
+    :param anchor: anchor point; default value ``Point(-1,-1)`` means that the anchor is at the kernel center. Only default value is supported now.
+
+    :param borderType: border mode used to extrapolate pixels outside of the image.
+
+The function applies adaptive bilateral filtering to the input image. This filter is similar to ``bilateralFilter``, in that dissimilarity from and distance to the center pixel is punished. Instead of using ``sigmaColor``, we employ the variance of pixel values in the neighbourhood.
