=== octave code to write ===
The following are missing targets that would be nice to have on future releases of the image package
* add inputParser to miscellaneous package
** write documentation for inputParser
** implement @inputParser/AddSwitch
* implement strel object for image package
* implement nlinfit as wrapper to leasqr once inputParser is finished
* make test and demo deal with tests and demos in .cc packages
:I don't like the first option. It's ugly and further pollutes the user namespace. And even if we have some Makefile that copies the .cc file at pkg install time, users won't know they have to make the call to test and demo differently. I guess demo and test functions would have to be modifed for that. I say just place the demos and tests on the .cc file. Later we can change pkg to copy the .cc file, and then change demo and test to look for those files if the function is .oct file. Tests are mainly used in development so users won't need them. Demos... well in the case of ellipj, it has not been working for a very long time so my guess is that people haven't been using it that much. What do you think?</pre>
* replacement for [http://www.mmorph.com/ morphology toolbox]
* port omero toolbox

* speed up {{codeline|regionprops}} for large images with many small objects (probably work around for loop with labeled == labelid)
* fix imhist
* support passing {{codeline|bwconncomp}} output to {{codeline|regionprops}} (and then fix {{codeline|bwpropfilt}} to use that instead of a labeled image)
* fix tiff_tag_reader
* ND support on {{codeline|imfilter}}
* finish iptcheckinput
* check if {{codeline|normxcorr2}} is Matlab compatible and investigate making use of {{codeline|fftconvn}} since it's likely to receive large input

I got involved with Octave on the Winter of 2010, at the end of my first year as PhD student. My project involved using a Matlab piece of code written by a collaborator but I refused to use it, I wanted free software. So I convinced the collaborators to release it under GPL and ported it to Octave (released as frapinator, but I really should go back and write it properly).

Since then, I have contributed to Octave many times, became maintainer of the Octave Forge project and its image package. While I have no formal education in programming or computer science, it was the freedom of Octave and its community that allowed me to learn so much.

Roadmap[edit]

The following are missing targets that would be nice to have on future releases of the image package

  • add ellipse properties to regionprops (see bug #44100) (done)
  • speed up regionprops for large images with many small objects (probably work around for loop with labeled == labelid)
  • support passing bwconncomp output to regionprops (and then fix bwpropfilt to use that instead of a labeled image)
  • ND support on imfilter
  • check if normxcorr2 is Matlab compatible and investigate making use of fftconvn since it's likely to receive large input
  • investigate implementing the missing deconvolution functions (see patch #8571)
  • anything else that is done or submitted before the above are done
