The reason why it tests didn't fail back in 3.2.4 was because conv2 was wrong and fftconv2 was replicating that wrongness. Now that conv2 has been fixed, the test that compares it with conv2 fails. Basically this has never worked and an error is indeed more appropriate here. Thank you, Carnë |

Talking to Carnë in IRC, it seems clear that the problem isn't that
the test is wrong but rather that fftconv2 is wrong here. It seems
like an actual bug.
OF list: fftconv2's vector-vector-matrix three-arg call seems
incorrect and seems to have been incorrect for some time. Can anyone
please confirm? These two calls should both be equal:
octave:1> conv2(1:3, 1:2, [1 2; 3 4; 5 6])
ans =
1 4 4
5 18 16
14 48 40
19 62 48
15 48 36
octave:2> fftconv2(1:3, 1:2, [1 2; 3 4; 5 6])
ans =
1 4 7 6
5 18 31 24
11 36 61 42
10 32 54 36
The upper result is correct. You can nobtain this result with
fftconv2(fftconv2([1 2; 3 4; 5 6,1:2),1:3), so I think this should be
fairly easy to fix.
Patches, anyone?

I've been meaning to write something like that for us for ages. However, it won't catch certain exceptions. For example, the function edge was not only GPL. One of its options had a user-written license which was stated in the middle of the file. This is no longer the case and we are rejecting such licenses http://octave.1599824.n4.nabble.com/removal-of-non-standard-licenses-in-Octave-Forge-td4645841.html The DEP5 format is still a bit too complicated to parse automatically and I don't want to cause problems to other distros. But I will try to add the list of copyright owners names to the copyright file too and run licensecheck to see if it struggles with anything. >>> On 11 November 2012 09:54, Rafael Laboissiere <ra...@la...> >>> wrote: >>> >>> 3) The function fftconv2 gives a wrong result when called like this: >>> "fftconv2 (vector1, vector2, matrix)", although this usage is advertised in >>> the help string.

Please see r11421. Well, IMHO it is not a good idea to allow function to give results that are known to be wrong. I will see with the other members of the DOG (Debian Octave Group) how we should proceed while waiting for the fix from upstream. Thanks, Rafael |

Fix with r11422. Can I further help with this by creating a proper COPYRIGHT file for the package?

You forgot to attach the patch. I don't know what changed to make this usage stop working so I only left a note on the source code and should not appear on the help string (at least it doesn't on my system). Do not remove the tests, mark them with xtest instead. I think I have done that before but apparently forgot to commit. I'd give a warning instead of an error since the reason it fails may be due to changes in the other functions it uses and users with different versions may actually get the correct results.

* Carnë Draug <car...@gm...> [2012-11-08 19:38]:
> a new release of the image package is out, version 2.0.0, by Carnë
> Draug.
Thanks for this new release, Carnë. I am in the process of preparing
the Debian package for it.
I noticed three issues in this tarball:
1) Although the large majority of the files are correctly encoded in
UTF-8, there are still some of them in Latin1:
$ file inst/* | grep ISO
inst/bwarea.m: ISO-8859 text
inst/bwperim.m: ISO-8859 text
inst/edge.m: ISO-8859 text
inst/fspecial.m: ISO-8859 text
inst/im2double.m: ISO-8859 text
inst/im2int16.m: ISO-8859 text
inst/im2single.m: ISO-8859 text
inst/im2uint16.m: ISO-8859 text
inst/im2uint8.m: ISO-8859 text
inst/imperspectivewarp.m: ISO-8859 text
inst/imremap.m: ISO-8859 text
inst/imresize.m: ISO-8859 text
inst/label2rgb.m: ISO-8859 text
This only affects the names of authors in the copyright notices, but is a
nuisance for generating the debian/copyright file for the Debian package.
2) The function 'bwmorph' calls 'erode' and 'dilate', which are
deprecated by the package itself. It would be good to change the code
to use imerode and imdilate.
3) The function fftconv2 gives a wrong result when called like this:
"fftconv2 (vector1, vector2, matrix)", although this usage is advertised
in the help string. For the Debian package, I am planning to apply the
patch attached below, which (i) removes the advertisement from the help
string, (ii) gives an error message when the function is called with the
said usage and (iii) drop the tests with the said usage.
If you could address the issues below in the next release, it would be
great.
Best,
Rafael

Hi, I think the best way to do this would be to start by adding your Octave interface to the linear-algebra package in Octave-Forge, then start working from there. The first step to do so woud be to upload your interface code here: https://sourceforge.net/p/octave/feature-requests so we can have a look and comment on it. c. P.S. there is a student here at Politecnico di Milano working on an implementation of the ILU preconditioner who might be interested in helping out. |

That's good. I have made a couple of simple changes to the package now but have no idea of its actual state as I can't really test it. My guess would be that it's a bit broken since it's quite old and Octave has changed a lot in the mean time. Please test it, and if possible, send us patches. Carnë |

A question: is there an implementation or a plan to implement bindings for ICC color profiles in the Image library? This would be very useful 1. to work with the data in existing images whose values reference a color space 2. to allow development of calibration/profiling algorithms There is some reference in the link below to the well-regarded lcms library, but as a beginner I wouldn't know how to bind this to Octave. However, if someone here is interested in making this part of the Image package I would be prepared to help with domain-specific knowledge. http://mirror.fcaglp.unlp.edu.ar/pub/octave/MAILING-LISTS/octave-sources/2001/1 On Thu, Nov 8, 2012 at 11:47 PM, Jordi Gutiérrez Hermoso <jo...@oc... > wrote: > On 8 November 2012 15:51, edmund ronald <edm...@gm...> wrote: > > > On Thu, Nov 8, 2012 at 8:38 PM, Carnë Draug <car...@gm...> > > wrote: > >> > >> Hi everyone > >> > >> a new release of the image package is out, version 2.0.0, by Carnë > Draug. > > > Also, is there documentation of the new features etc? > > I would like to advertise partial support of N-dimensional binary > images (the bw* family of functions).

I would like to advertise partial support of N-dimensional binary images (the bw* family of functions). I worked on bwlabeln and modified a few functions where it was easy to do so to make them work N-dimensionally. The biggest missing one here that I am planning to work on next is bwdist and perhaps bwconncomp. Consider this an invitation to help with that development effort too. :-) - Jordi G. H. |

You can try uninstalling Macports' image package and using "pkg install
-forge image" from Octave to install the new version; that works in _my_
packaging of Octave, at least. It's probably safest to do that as a
user rather than doing a global install.

Yes. At your Octave prompt run:
news ("image")

Hi, I just installed octave-devel (Octave 3.6.3) from MacPorts on Mac OS X 10.6.8 If I want to use the new image package what do I need to do? Can I unload the old one and load in the new one somehow? Also, is there documentation of the new features etc?

Carlo de Falco just polished some presentation slides I started for
OctConf 2012. The result looks very nice and can be used for anyone
who wants to give a talk promoting and explaining Octave:
http://jordi.platinum.linux.pl/octave/what-is-octave.pdf
If you want to modify these for a presentation you may want to give
yourself, please feel free to do so. Their LaTeX source is in this
Mercurial repository:
http://inversethought.com/hg/what-is-octave/
Patches are also very welcome. ;-)
