This repo contains [DepthProNormalizedInverseDepthPruned10QuantizedLinear.mlpackage](DepthProNormalizedInverseDepthPruned10QuantizedLinear.mlpackage)(745 MB).

`Normaized Inverse Depth` means that the model will output values between $[0,1]$ where 1 is the closest pixel to the camera, and 0 is the furthest pixel from the camera.

This model was first pruned to 10% sparsity, then the weights were linearly quantized.

# 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

### Inputs

- `image`: $1536 \times 1536$ 3 color image ($[1 \times 3 \times 1536 \times 1536]$ ImageType).

### Outputs

- `normalizedInverseDepth` 1536x1536 monochrome image ($[1 \times 1 \times 1536 \times 1536]$ ImageType).

# Conversion Tutorial 

The [`huggingface/coreml-examples`](https://github.com/huggingface/coreml-examples/blob/main/tutorials/DepthPro/depth_pro_coreml_guide.ipynb) repository contains sample conversion code for `DepthProNormalizedInverseDepthPruned10QuantizedLinear.mlpackage` and other models.

# Swift Integration

The [`huggingface/coreml-examples`](https://github.com/huggingface/coreml-examples/blob/main/DepthProSample/README.md) repository contains sample Swift code for `DepthProNormalizedInverseDepthPruned10QuantizedLinear.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.
