# DPT ## Overview The DPT model was proposed in [Vision Transformers for Dense Prediction](https://huggingface.co/papers/2103.13413) by René Ranftl, Alexey Bochkovskiy, Vladlen Koltun. DPT is a model that leverages the [Vision Transformer (ViT)](vit) as backbone for dense prediction tasks like semantic segmentation and depth estimation. The abstract from the paper is the following: *We introduce dense vision transformers, an architecture that leverages vision transformers in place of convolutional networks as a backbone for dense prediction tasks. We assemble tokens from various stages of the vision transformer into image-like representations at various resolutions and progressively combine them into full-resolution predictions using a convolutional decoder. The transformer backbone processes representations at a constant and relatively high resolution and has a global receptive field at every stage. These properties allow the dense vision transformer to provide finer-grained and more globally coherent predictions when compared to fully-convolutional networks. Our experiments show that this architecture yields substantial improvements on dense prediction tasks, especially when a large amount of training data is available. For monocular depth estimation, we observe an improvement of up to 28% in relative performance when compared to a state-of-the-art fully-convolutional network. When applied to semantic segmentation, dense vision transformers set a new state of the art on ADE20K with 49.02% mIoU. We further show that the architecture can be fine-tuned on smaller datasets such as NYUv2, KITTI, and Pascal Context where it also sets the new state of the art.* DPT architecture. Taken from the original paper. This model was contributed by [nielsr](https://huggingface.co/nielsr). The original code can be found [here](https://github.com/isl-org/DPT). ## Usage tips DPT is compatible with the [AutoBackbone](/docs/transformers/v4.57.1/en/main_classes/backbones#transformers.AutoBackbone) class. This allows to use the DPT framework with various computer vision backbones available in the library, such as `VitDetBackbone` or `Dinov2Backbone`. One can create it as follows: ```python from transformers import Dinov2Config, DPTConfig, DPTForDepthEstimation # initialize with a Transformer-based backbone such as DINOv2 # in that case, we also specify `reshape_hidden_states=False` to get feature maps of shape (batch_size, num_channels, height, width) backbone_config = Dinov2Config.from_pretrained("facebook/dinov2-base", out_features=["stage1", "stage2", "stage3", "stage4"], reshape_hidden_states=False) config = DPTConfig(backbone_config=backbone_config) model = DPTForDepthEstimation(config=config) ``` ## Resources A list of official Hugging Face and community (indicated by 🌎) resources to help you get started with DPT. - Demo notebooks for [DPTForDepthEstimation](/docs/transformers/v4.57.1/en/model_doc/dpt#transformers.DPTForDepthEstimation) can be found [here](https://github.com/NielsRogge/Transformers-Tutorials/tree/master/DPT). - [Semantic segmentation task guide](../tasks/semantic_segmentation) - [Monocular depth estimation task guide](../tasks/monocular_depth_estimation) If you're interested in submitting a resource to be included here, please feel free to open a Pull Request and we'll review it!

It is used to instantiate an DPT model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the DPT [Intel/dpt-large](https://huggingface.co/Intel/dpt-large) architecture. Configuration objects inherit from [PretrainedConfig](/docs/transformers/v4.57.1/en/main_classes/configuration#transformers.PretrainedConfig) and can be used to control the model outputs. Read the documentation from [PretrainedConfig](/docs/transformers/v4.57.1/en/main_classes/configuration#transformers.PretrainedConfig) for more information. Example: ```python >>> from transformers import DPTModel, DPTConfig >>> # Initializing a DPT dpt-large style configuration >>> configuration = DPTConfig() >>> # Initializing a model from the dpt-large style configuration >>> model = DPTModel(configuration) >>> # Accessing the model configuration >>> configuration = model.config ``` to_dicttransformers.DPTConfig.to_dicthttps://github.com/huggingface/transformers/blob/v4.57.1/src/transformers/models/dpt/configuration_dpt.py#L280[] Serializes this instance to a Python dictionary.

This choice is based on empirical observations, as detailed here: https://github.com/huggingface/transformers/pull/38157 ensure_multiple_of (`int`, *optional*, defaults to 1) : If `do_resize` is `True`, the image is resized to a size that is a multiple of this value. Can be overridden by `ensure_multiple_of` in `preprocess`. size_divisor (`int`, *optional*) : If `do_pad` is `True`, pads the image dimensions to be divisible by this value. This was introduced in the DINOv2 paper, which uses the model in combination with DPT. keep_aspect_ratio (`bool`, *optional*, defaults to `False`) : If `True`, the image is resized to the largest possible size such that the aspect ratio is preserved. Can be overridden by `keep_aspect_ratio` in `preprocess`. do_reduce_labels (`bool`, *optional*, defaults to `self.do_reduce_labels`) : Whether or not to reduce all label values of segmentation maps by 1. Usually used for datasets where 0 is used for background, and background itself is not included in all classes of a dataset (e.g. ADE20k). The background label will be replaced by 255. **Returns:** ```` - **data** (`dict`) -- Dictionary of lists/arrays/tensors returned by the __call__ method ('pixel_values', etc.). - **tensor_type** (`Union[None, str, TensorType]`, *optional*) -- You can give a tensor_type here to convert the lists of integers in PyTorch/TensorFlow/Numpy Tensors at initialization. #### post_process_semantic_segmentation[[transformers.DPTImageProcessorFast.post_process_semantic_segmentation]] [Source](https://github.com/huggingface/transformers/blob/v4.57.1/src/transformers/models/dpt/image_processing_dpt_fast.py#L253) Converts the output of [DPTForSemanticSegmentation](/docs/transformers/v4.57.1/en/model_doc/dpt#transformers.DPTForSemanticSegmentation) into semantic segmentation maps.

Each entry of each `torch.Tensor` correspond to a semantic class id. #### post_process_depth_estimation[[transformers.DPTImageProcessorFast.post_process_depth_estimation]] [Source](https://github.com/huggingface/transformers/blob/v4.57.1/src/transformers/models/dpt/image_processing_dpt_fast.py#L364) Converts the raw output of `DepthEstimatorOutput` into final depth predictions and depth PIL images.
