# pyJBU

A Python implementation of Joint Bilateral Upsampling [[1]](#ref1).

## Installation

```

pip install -r requirements.txt

```

## Usage

```

usage: jbu.py [-h] [--radius RADIUS] [--sigma-spatial SIGMA_SPATIAL]

              [--sigma-range SIGMA_RANGE]

              source reference output

Perform Joint Bilateral Upsampling with a source and reference image

positional arguments:

  source                Path to the source image

  reference             Path to the reference image

  output                Path to the output image

optional arguments:

  -h, --help            show this help message and exit

  --radius RADIUS       Radius of the filter kernels (default: 2)

  --sigma-spatial SIGMA_SPATIAL

                        Sigma of the spatial weights (default: 2.5)

  --sigma-range SIGMA_RANGE

                        Sigma of the range weights (default: standard

                        deviation of the reference image)

```

The source image will be upsampled to the resolution of the reference image. The result will be written to the specified path of the output image.
