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.
