Intensity, gradient intensity and local structure are computed at different scales thanks to Gaussian blurring. Parameters ---------- image : ndarray Input image, which can be grayscale or multichannel. intensity : bool, default True If True, pixel intensities averaged over the different scales are added to the feature set. edges : bool, default True If True, intensities of local gradients averaged over the different scales are added to the feature set. texture : bool, default True If True, eigenvalues of the Hessian matrix after Gaussian blurring at different scales are added to the feature set. sigma_min : float, optional Smallest value of the Gaussian kernel used to average local neighborhoods before extracting features. sigma_max : float, optional Largest value of the Gaussian kernel used to average local neighborhoods before extracting features. num_sigma : int, optional Number of values of the Gaussian kernel between sigma_min and sigma_max. If None, sigma_min multiplied by powers of 2 are used. num_workers : int or None, optional The number of parallel threads to use. If set to ``None``, the full set of available cores are used. channel_axis : int or None, optional If None, the image is assumed to be a grayscale (single channel) image. Otherwise, this parameter indicates which axis of the array corresponds to channels. .. versionadded:: 0.19 ``channel_axis`` was added in 0.19. Returns ------- features : np.ndarray Array of shape ``image.shape + (n_features,)``. When `channel_axis` is not None, all channels are concatenated along the features dimension. (i.e. ``n_features == n_features_singlechannel * n_channels``) z[At least one of `intensity`, `edges` or `textures`must be True for features to be computed..c 3NK|]}td|f yw).)r7r8r9rMrNrOrPN)rU) .0dimr8imager7rOrPrNrMr9s r z,multiscale_basic_features..sE   0 #s(O#  s"%r$) any ValueErrorr(newaxismoveaxisr&shaperIrJrKrLstack) r\r7r8r9rMrNrOrPrV all_resultsrTouts ```````` rmultiscale_basic_featuresrfssr  5'* + 8  c2::o&   E<4  R) KIOO11+>?H ((8" %C Jr)TTT)TTTg?NN)rJrnumpyr(skimagerrskimage.util.dtyper_shared._dependency_checksrconcurrent.futuresr r contextlibr r0r;rUrfrrrrns3$-0E1&-&59    @J  SSr
