Parameters ---------- image: numpy.ndarray Image with shape :math:`h\times w \times 3` radius: int Radius of local window size, defaults to 1, i.e. only adjacent pixels are considered. The size of the local window is given as :math:`(2 r + 1)^2`, where :math:`r` denotes the radius. A larger radius might lead to violated color line constraints, but also favors further propagation of information within the image.
