PROJECTS\API\Inventory\templateJSON\kerjaOCR\Lib\site-packages\skimage/future/trainable_segmentation.pyrr s r rc*eZdZdZddZdZdZdZy)TrainableSegmenteraEstimator for classifying pixels. Parameters ---------- clf : classifier object, optional classifier object, exposing a ``fit`` and a ``predict`` method as in scikit-learn's API, for example an instance of ``RandomForestClassifier`` or ``LogisticRegression`` classifier. features_func : function, optional function computing features on all pixels of the image, to be passed to the classifier. The output should be of shape ``(m_features, *labels.shape)``. If None, :func:`skimage.feature.multiscale_basic_features` is used.
