This final project was done as part of the 15-663 Fall 2020 course on Computational Photography taught by Prof. Ioannis Gkioulekas at Carnegie Mellon University. This project implements the paper The ”Vertigo Effect” on Your Smartphone: Dolly zoom via single shot view synthesis. It also extends this by using light field cameras, with the help of the plenpy library. The results and implementation details are provided in the PDF.
The rest of this README is retained as is from plenpy.
This is a Python package to calibrate, process and analyse (hyperspectral) light field images as well as (hyper)spectral images from either real cameras (e.g. Lytro) or synthetic/rendered images.
Note: The package is still undergoing API altering changes with each minor release.

Have a look at our User Documentation for notes on usage and some examples to get you started.
For a quick tryout of plenpy, you can use our latest Docker Image.
You can install plenpy
directly from PyPi via pip
:
$ pip install plenpy
That's it!
Plenpy requires python >= 3.6
as it relies on Python syntax that has
been introduced in Python 3.6 such as f-strings or type hinting.
Plenpy is currently tested on Python 3.6, 3.7, and 3.8.
The package dependencies are resolved automatically upon installation using pip
.
For development and testing dependencies, see the requirements.txt
file.
The package dependencies are stated in setup.py
.
If you want to install from source, the installation using make
is straightforward and installs
plenpy
and its runtime dependencies automatically.
If make
is not available, or if you are running Windows, see below.
Caution: A system wide installation using sudo
is easy and possible but
discouraged. Installing in a environment is recommended.
To install plenpy
, first clone the project's git repository to
a location of your desire and change directory to the project:
$ cd <path-to-plenpy>/
$ git clone [email protected]:iiit-public/plenpy.git
$ cd plenpy
Then, install the library via:
$ make
Or, to have an editable install of plenpy, using
$ make editable
If no errors occur, you can check if the installation was successful by running the unit tests:
$ make test
That's it! The package should now be available.
If make
is not available on your system, the installation via pip
is also straightforward. Instead of invoking make
,
install by calling (e.g. from the Anaconda prompt)
$ pip install -r requirements.txt .
Please note the .
at the end, referring to the current folder
<path-to-plenpy>/plenpy
.
You can manually run the tests using pytest
:
$ pytest <path-to-plenpy>/test/
Uninstall plenpy
using
$ pip uninstall plenpy
The documentation can be found here.
You can also build the documentation yourself:
The documentation is build using Sphinx. To install all necessary dependencies for the documentation, run
$ cd <path-to-plenpyr>
$ make
$ pip install -r docs/requirements.txt
$ cd docs
$ sphinx-apidoc -f -o ./ ../plenpy/
$ make html
This will create the full plenpy
documentation in the
docs/_build/html
folder.
If you are interested in contributing to plenpy
, feel free to create an issue or
fork the project and submit a merge request. As this project is still undergoing
restructuring and extension, help is always welcome!
Please stick to the PEP 8 Python coding styleguide.
The docstring coding style of the reStructuredText follows the googledoc style.
