<PRE>Le mardi 19 juillet 2011 à 02:04 +0200, Philippe DIDIER a écrit :
><i> It's in the title !
</I>><i> The use of the Scale Invariant Feature Transform (SIFT) algorythm
</I>><i> allowing to find control points to build panorama with several pictures
</I>><i> is restricted by a US patent... this algorythm is the basis of
</I>><i> autopano-sift and autopano-sift-C !
</I>><i>
</I>><i> hugin (a pano builder program) brings some patents problems with some of
</I>><i> its tools : this one is an optional tool, and we can use hugin without
</I>><i> it... mostly since 2010.4 version of hugin which ships its own patent
</I>><i> free control point generator which is quite as good as autopano ;)
</I>><i>
</I>><i>
</I>><i> the other rpm bringing patent problem is libpano13 (required by hugin) :
</I>><i> two versions exist yet for mageia:
</I>><i> - one in core repository with a limited field of view (160°) and giving
</I>><i> this limit to hugin (no patent problem though !)
</I>><i> - one in tainted repository without limitation (but infringing US and
</I>><i> Japan patents) allowing to build 360° panorama
</I>
What are the patents number ?
