the image to put the zero-frequency component in the center of the
image. This contribution comes with a filter to perform this
transform.

Summary:
Similarly to the fftshift and ifftshift functions of Matlab, this filter swaps the "half-spaces" of the input image along each dimension.
Evidence:
The author provides two input images and their corresponding outputs using or not the "inverse" option.
Open Science:
The author provides the source code and an example to reproduce his experiments. He also provides the images.
Reproducibility:
I compiled the code using CMake 2.4 and Visual C++ 2005 Express on Windows XP SP2, there is no error or warning. I ran it with different types of image supported by ITK (png, jpg, tiff, gif, 24-bit bitmap) and it works great.
The results are easily reproducible with the information from the paper.
Use of Open Source Software:
The authors use ITK.
Open Source Contributions:
The author provides his source code and describes clearly how to use it.
Code Quality:
The code is easy to read and all the necessary comments are presents.
Requests for additional information from authors:
Maybe the author could shortly describe how the filter puts the zero-frequency component in the center of the image (swapping parts of the image) in the pdf file.
