The image is read sequencially and when a segment\n is identified it is inserted at a right place is a set of valid polygons.\n This process can grow up polygons on bounds, or merge polygons together.\n\n The algorithm can take care of a mask. If a pixel is invalidated by a\n non-zero value of the mask at it's location, the computation of the pattern\n cancelled and no segements are generated.\n\n This implementation based on merge allow to use divide and conquer\n implementation in multi process using OpenMP.The image is subdivised into\n many tiles, each one is processed independantly. The result is finally\n reduced by consecutives polygon merges.\n\n The OpenMP group size can also by used to skip part of the image using\n pre-computed informations. `use_minmax_cache` can enable the computation of\n minimum and maximum pixel levels available on each tile groups. It was\n designed to improve the efficiency of the extraction of many contour levels\n from the same gradient image.\n\n Finally the implementation provides an implementation to reach polygons\n (:meth:`find_contours`) or pixels (:meth:`find_pixels`) from the iso-valued\n data.\n\n .. code-block:: python\n\n # Example using a mask\n shape = 100, 100\n image = numpy.random.random(shape)\n mask = numpy.random.random(shape) < 0.01\n ms = MarchingSquaresMergeImpl(image, mask)\n polygons = ms.find_contours(level=0.5)\n for polygon in polygons:\n print(polygon)\n\n .. code-block:: python\n\n # Example using multi requests\n shape = 1000, 100""0\n image = numpy.random.random(shape)\n ms = MarchingSquaresMergeImpl(image)\n levels = numpy.arange(0, 1, 0.05)\n for level in levels:\n polygons = ms.find_contours(level=level)\n\n .. code-block:: python\n\n # Efficient cache using multi requests\n shape = 1000, 1000\n image = numpy.arange(shape[0] * shape[1]) / (shape[0] * shape[1])\n image.shape = shape\n ms = MarchingSquaresMergeImpl(image, use_minmax_cache=True)\n levels = numpy.arange(0, 1, 0.05)\n for level in levels:\n polygons = ms.find_contours(level=level)\n\n :param numpy.ndarray image: Image to process.\n If the image is not a continuous array of native float 32bits, the data\n will be first normalized.
