## Use Case and High-Level Description

This is a model for monocular depth estimation trained on the NYU Depth V2 dataset, as described in the paper Deeper Depth Prediction with Fully Convolutional Residual Networks, where it is referred to as ResNet-UpProj. The model input is a single color image. The model output is an inverse depth map that is defined up to an unknown scale factor. More details can be found in the following repository.

## Specification

Metric Value
Type Monodepth
GFLOPs 63.5421
MParams 34.5255
Source framework TensorFlow*

## Accuracy

Metric Value
RMSE 0.573
log10 0.055
rel 0.127

Accuracy numbers obtained on NUY Depth V2 dataset. The log10 metric is logarithmic absolute error, defined as abs(log10(gt) - log10(pred)), where gt - ground truth depth map, pred - predicted depth map. The rel metric is relative absolute error defined as absolute error normalized on ground truth depth map values (abs(gt - pred) / gt, where gt - ground truth depth map, pred - predicted depth map).
