tiff2csv

This is a simple python package for processing .tif image data and outputting .csv files. The intention is to operate on a sequence of .tif images and, based on a given discretization size, output a .csv file containing the voxel data. You can find the Github repository on https://github.com/alhermann/tiff2csv.git.

Getting started

You can use the Python package manager Pip for downloading the module from https://pypi.org/project/tiff2csv.

pip3 install tiff2csv

Example

Suppose you have stored a stack of .tif image files in an upper subdirectory called ../tiffs. In order to run the main module, you have to provide this path as a mandatory argument. For the description of additional arguments, you can use the -hor --help flag

python3 -m tiff2csv --help

which produces the following output:

usage: __main__.py [-h] [-n imgNum] [-r resolution] [-d dFile] [-p pooling] sFile [sFile ...]

Script that reads a sequence of .tif files and outputs .csv file of voxel data
to user specified directory

positional arguments:
  sFile          the source file of the .tif image sequence

optional arguments:
  -h, --help     show this help message and exit
  -n imgNum      number of .tif images
  -r resolution  voxel resolution in the .tif images
  -d dFile       the destination directory where the output should go to
  -p pooling     optionally activate 2D pooling on the input images

For an exemplary CT image resolution of 5mu the following command runs a max-pooling compression on the input image data files and outputs a voxelization.csv voxel data file to user specified (in this case parent) directory.

python3 -m tiff2csv ../tiffs/ -r 5e-6 -d ../ -p True
