# DepthPro CoreML Models

DepthPro is a monocular depth estimation model. This means that it is trained to predict depth on a single image.

## Model Inputs and Outputs

### DepthPro Normalized Inverse Depth Models

#### Inputs

- `pixel_values`: 1536x1536 3 color image.

#### Outputs

- `normalized_inverse_depth` 1536x1536 monochrome image.

### DepthPro Models

#### Inputs

- `pixel_values`: 1536x1536 3 color image.
- `original_widths`: 1x1x1x1 Tensor containing the original width of the image before resizing.

#### Outputs

- `depth_meters`: 1x1x1536x1536 Tensor containing depth in meters.

## Download

Install `huggingface-cli`

```bash
brew install huggingface-cli
```

To download one of the `.mlpackage` folders to the `models` directory:

```bash
huggingface-cli download \
  --local-dir models --local-dir-use-symlinks False \
  KeighBee/coreml-DepthPro \
  --include "DepthProNormalizedInverseDepth-pruned10-Qlinear.mlpackage/*" "DepthPro-pruned10-Qlinear.mlpackage/*"
```

To download everything, skip the `--include` argument.

## Integrate in Swift apps

The [`huggingface/coreml-examples`](https://github.com/huggingface/coreml-examples/blob/main/DepthProSample/README.md) repository contains sample Swift code for `DepthProNormalizedInverseDepth-pruned10-Qlinear.mlpackage` and other models. See [the instructions there](https://github.com/huggingface/coreml-examples/tree/main/DepthProSample) to build the demo app, which shows how to use the model in your own Swift apps.
