Skimage.measure.find_contours array level

WebbContour finding We use a marching squares method to find constant valued contours in an image. In skimage.measure.find_contours, array values are linearly interpolated to … WebbParameters: array: 2D ndarray of double. Input data in which to find contours. level: float. Value along which to find contours in the array. fully_connected: str, {‘low’, ‘high’}. Indicates whether array elements below the given level value are to be considered fully-connected (and hence elements above the value will only be face connected), or vice-versa.

Why find_contours can not give a exact outline?
