Parameters ---------- image : ndarray RGB or grayscale nD image. The input image is converted to grayscale before computing the blur metric. h_size : int, optional Size of the re-blurring filter. channel_axis : int or None, optional If None, the image is assumed to be grayscale (single-channel). Otherwise, this parameter indicates which axis of the array corresponds to color channels. reduce_func : callable, optional Function used to calculate the aggregation of blur metrics along all axes. If set to None, the entire list is returned, where the i-th element is the blur metric along the i-th axis. Returns ------- blur : float (0 to 1) or list of floats Blur metric: by default, the maximum of blur metrics along all axes. Notes ----- `h_size` must keep the same value in order to compare results between images. Most of the time, the default size (11) is enough. This means that the metric can clearly discriminate blur up to an average 11x11 filter; if blur is higher, the metric still gives good results but its values tend towards an asymptote.
