=== Improvements to n-dimensional image processing ===
=== Improvements to N-dimensional image processing ===


<strike>
The image package has partial functionality for N-dimensional images. These images do exist in practice for example in medical imaging where slices from scans are assembled to form anatomical 3D images, or even exposures taken over time on different wavelengths can result in 5D images. As part of GSoC 2013, the core functions {{codeline|imwrite}} and {{codeline|imread}} were extended to better support this type of images. Likewise, many functions in the image package, mostly morphology operators, were expanded to deal with this type of images. Still, many are left to, specially image transformation and analysis of ROIs.
The image package has partial functionality for n-dimensional images. These images do exist in practice for example in medical imaging where slices from scans are assembled to form anatomical 3d images, or even exposures taken over time on different wavelengths can result in 5d images. All of the base functions should be modified so that they can handle n-dimensional images, and corresponding Matlab functions such as <code>bwconncomp</code> or n-dimensional version of <code>bwdist</code> should be implemented. In addition,
the core functions {{codeline|imwrite}} and {{codeline|imread}} need to be adjusted to deal with this type images (usually multipage TIFF).


'''Required skills''': Mostly m-file scripting, perhaps some C++. Familiarity with common CS algorithms would be useful.
Note that while many of the functions in the image package will not complain about ND images, they are actually not correctly implemented and will give incorrect results.

This was mostly accomplished in 2013 GSoC, see the Image package NEWS file [https://sourceforge.net/p/octave/image/ci/default/tree/NEWS] for details
