pyJBU

A Python implementation of Joint Bilateral Upsampling [1].

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.
