This pipeline predicts masks of objects and their classes. Example: ```python >>> from transformers import pipeline >>> segmenter = pipeline(model="facebook/detr-resnet-50-panoptic") >>> segments = segmenter("https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png") >>> len(segments) 2 >>> segments[0]["label"] 'bird' >>> segments[1]["label"] 'bird' >>> type(segments[0]["mask"]) # This is a black and white mask showing where is the bird on the original image. >>> segments[0]["mask"].size (768, 512) ``` This image segmentation pipeline can currently be loaded from [`pipeline`] using the following task identifier: `"image-segmentation"`. See the list of available models on [huggingface.co/models](https://huggingface.co/models?filter=image-segmentation).

Args: inputs (`str`, `list[str]`, `PIL.Image` or `list[PIL.Image]`): The pipeline handles three types of images: - A string containing an HTTP(S) link pointing to an image - A string containing a local path to an image - An image loaded in PIL directly The pipeline accepts either a single image or a batch of images. Images in a batch must all be in the same format: all as HTTP(S) links, all as local paths, or all as PIL images. subtask (`str`, *optional*): Segmentation task to be performed, choose [`semantic`, `instance` and `panoptic`] depending on model capabilities. If not set, the pipeline will attempt tp resolve in the following order: `panoptic`, `instance`, `semantic`. threshold (`float`, *optional*, defaults to 0.9): Probability threshold to filter out predicted masks. mask_threshold (`float`, *optional*, defaults to 0.5): Threshold to use when turning the predicted masks into binary values. overlap_mask_area_threshold (`float`, *optional*, defaults to 0.5): Mask overlap threshold to eliminate small, disconnected segments. timeout (`float`, *optional*, defaults to None): The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and the call may block forever. Return: If the input is a single image, will return a list of dictionaries, if the input is a list of several images, will return a list of list of dictionaries corresponding to each image. The dictionaries contain the mask, label and score (where applicable) of each detected object and contains the following keys: - **label** (`str`) -- The class label identified by the model. - **mask** (`PIL.Image`) -- A binary mask of the detected object as a Pil Image of shape (width, height) of the original image. Returns a mask filled with zeros if no object is found. - **score** (*optional* `float`) -- Optionally, when the model is capable of estimating a confidence of the "object" described by the label and the mask. imagesNzICannot call the image-classification pipeline without an inputs argument!)poprrr.r-r!r"r#r.hs , cCst||d}|j|jfg}|jjjjdkr|dur8i}n d|gi}|jf|gdd|}|jdkrp| |j }|j |dd|jjj |jdd|d<n&|j|gdd}|jdkr| |j }||d <|S) N)r(ZOneFormerConfigZ task_inputspt)r/return_tensors max_length)paddingr3r2Z input_ids target_size) rheightwidthmodelconfigr__name__image_processorrtoZdtype tokenizerZ task_seq_len)rimager$r(r5rr*r"r"r# preprocesss,       z$ImageSegmentationPipeline.preprocesscCs&|d}|jfi|}||d<|S)Nr5)r0r8)rZ model_inputsr5 model_outputsr"r"r#_forwards z"ImageSegmentationPipeline._forward??cCsd}|dvr"t|jdr"|jj}n|dvr>t|jdr>|jj}|dur||||||ddd}g}|d} |d D]Z} | | d kd } tj| tj d d } |j j j | d} | d} | | | | dqtn|dvrht|jdrh|jj||ddd}g}|} t| }|D]H} | | kd } tj| tj d d } |j j j | } | d| | dqntd|dt|j |S)N>ZpanopticN"post_process_panoptic_segmentation>instanceN"post_process_instance_segmentationr5)r%r&r' target_sizesr segmentationZ segments_infoidL)modeZlabel_idscore)rMlabelmask>ZsemanticN"post_process_semantic_segmentation)rGzSubtask z is not supported for model )hasattrr;rDrFrZ fromarraynumpyZastypenpZuint8r8r9Zid2labelappendrPuniquertype)rr@r$r%r&r'fnoutputs annotationrHsegmentrOrNrMlabelsr"r"r# postprocesssN    z%ImageSegmentationPipeline.postprocess)NN)NrBrCrC)r: __module__ __qualname____doc__Z_load_processorZ_load_image_processorZ_load_feature_extractorZ_load_tokenizerrr)rrstrrlistdictr.r?rAr\ __classcell__r"r"r!r#rs$# (4&2 r)typingrrrrRrSutilsrrrr r baser r ZPILrZ image_utilsrZmodels.auto.modeling_autorrrrZ get_loggerr:loggerrr"r"r"r#s
