<font size="-1"><font face="Tahoma">Hi everyone!<br>
<br>
It was got discussion today in #lbmv at <a href="http://irc.freenode.net" target="_blank">irc.freenode.net</a> related
on forcing pattern/search area be square.<br>
<br>
Main question: is non-square shape of marker useful in motion
tracking workflow?<br>
<br>
Some quick cases i could think could be solved just adding
offset to search area or by resizing this areas. But we've
checked some tracking applications and they allow to use
non-square markers. So</font></font><font size="-1"><font face="Tahoma"> i'm not sure it'll be good idea to stick to
squares.<br>
<br>
P.S. From UI point of view, search are could be rectangular,
just "missing" areas could be filled with black when it's
passing to libmv which would probably be optimized for squares.<br>
