Or, in the case of #HOUGH_GRADIENT method you may set maxRadius to a negative number\n.   to return centers only without radius search, and find the correct radius using an additional procedure.\n.   \n.

The function cv::distanceTransform calculates the approximate or precise distance from every binary\n.   image pixel to the nearest zero pixel. For zero image pixels, the distance will obviously be zero.\n.   \n.   When maskSize == #DIST_MASK_PRECISE and distanceType == #DIST_L2 , the function runs the\n.   algorithm described in @cite Felzenszwalb04 . This algorithm is parallelized with the TBB library.\n.   \n.   In other cases, the algorithm @cite Borgefors86 is used. This means that for a pixel the function\n.   finds the shortest path to the nearest zero pixel consisting of basic shifts: horizontal, vertical,\n.   diagonal, or knight's move (the latest is available for a \\f$5\\times 5\\f$ mask). The overall\n.   distance is calculated as a sum of these basic distances. Since the distance function should be\n.   symmetric, all of the horizontal and vertical shifts must have the same cost (denoted as a ), all\n.   the diagonal shifts must have the same cost (denoted as `b`), and all knight's moves must have the\n.   same cost (denoted as `c`). For the #DIST_C and #DIST_L1 types, the distance is calculated\n.   precisely, whereas for #DIST_L2 (Euclidean distance) the distance can be calculated only with a\n.   relative error (a \\f$5\\times 5\\f$ mask gives more accurate results). For `a`,`b`, and `c`, OpenCV\n.   uses the values suggested in the original paper:\n.   - DIST_L1: `a = 1, b = 2`\n.   - DIST_L2:\n.       - `3 x 3`: `a=0.955, b=1.3693`\n.       - `5 x 5`: `a=1, b=1.4, c=2.1969`\n.   - DIST_C: `a = 1, b = 1`\n.   \n.   Typically, for a fast, coarse distance estimation #DIST_L2, a \\f$3\\times 3\\f$ mask is used. For a\n.   more accurate distance estimation #DIST_L2, a \\f$5\\times 5\\f$ mask or the precise algorithm is used.\n.   Note that both the precise and the approximate algorithms are linear on the number of pixels.\n.   \n.   This variant of the function does not only compute the minimum distance for each pixel \\f$(x, y)\\f$\n.   but also identifies the nearest connected component consisting of zero pixels\n.   (labelType==#DIST_LABEL_CCOMP) or the nearest zero pixel (labelType==#DIST_LABEL_PIXEL). Index of the\n.   component/pixel is stored in `labels(x, y)`. When labelType==#DIST_LABEL_CCOMP, the function\n.   automatically finds connected components of zero pixels in the input image and marks them with\n.   distinct labels. When labelType==#DIST_LABEL_CCOMP, the function scans through the input image and\n.   marks all the zero pixels with distinct labels.\n.   \n.   In this mode, the complexity is still linear. That is, the function provides a very fast way to\n.   compute the Voronoi diagram for a binary image.
