the image to put the zero-frequency component in the center of the
image. This contribution comes with a filter to perform this
Similarly to the fftshift and ifftshift functions of Matlab, this filter swaps the "half-spaces" of the input image along each dimension.
The author provides two input images and their corresponding outputs using or not the "inverse" option.
The author provides the source code and an example to reproduce his experiments. He also provides the images.
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.
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.
