This is a script that returns an integral image suitable for light field images given a folder of images. It supports downsampling the images before generating the integral image.
Each file in the folder needs to have the following filename format:
<x>-<y>.<image format>
Where:
x: X value, or location from left edgey: Y value, or location from top edgeimage format: Any image format thatpillowsupports, or Nikon RAW format (NEF).
For example, the image at x-value 2 and y-value 7 may have a filename 2-7.png.
Install dependencies first with pip install -r requirements.txt
usage: lfgen [-h] [-r RATIO] [-o OUTPUT] [--fov-x FOV_X] [--fov-y FOV_Y] [-j JOBS] [--flip-y] directory
Generates a light field integral image from a folder of images
positional arguments:
directory Source directory
options:
-h, --help show this help message and exit
-r RATIO, --ratio RATIO
Downsampling ratio to use
-o OUTPUT, --output OUTPUT
Output filename, default is stdout
--fov-x FOV_X Simulate a restricted horizontal field of view
--fov-y FOV_Y Simulate a restricted vertical field of view
-j JOBS, --jobs JOBS Number of jobs
--flip-y Flip images vertically
The output integral image is an LF file with the config file and image inside it.
The following is a 4x4 integral image downscaled down to 10% and cropped to 45 degrees in each dimension
Using this command
python -m lfgen.main --fov-x 45 --fov-y 45 -r 0.1 -o output.lf
