oujou has always been an<br />
expensive package. At $10,000 it’s<br />
probably the costliest matchmoving<br />
solution available. For that kind of payout,<br />
you’d expect it to deliver something<br />
special. It doesn’t disappoint – the<br />
software will save you a huge amount<br />
of time, and spare you from the ravages<br />
of matchmoving boredom.<br />
Some 2D-to-3D packages require you<br />
to manually place 2D markers on certain<br />
points in an image and then track them<br />
in 2D before finally extracting the 3D<br />
scene information. This process can be<br />
both time-consuming and tedious, and<br />
requires that you have a least a few goes<br />
before discovering what and where the<br />
best tracking points in the footage are.<br />
Along with a handful of matchmoving<br />
applications, Boujou is a totally automatic<br />
matchmoving solution. Once footage is<br />
loaded you can tell the program to<br />
analyze each frame and choose the<br />
2D tracking points itself. There’s no<br />
need for human input at all.<br />
There are two main benefits of this<br />
automatic process. Firstly, the software is<br />
able to input a much larger number of<br />
tracking points than you would be able<br />
to reasonably do manually. This helps<br />
to reduce errors in the solution since<br />
the data is averaged over a greater<br />
number of tracking points. Secondly,<br />
the program can automatically add new<br />
points to track as they enter the frame.<br />
This is very difficult to do manually.<br />
The mask<br />
Moving objects in the scene can<br />
throw out the auto-tracking solution<br />
by contaminating the static scene data.<br />
Since Boujou doesn’t use any kind of<br />
artificial intelligence to select tracking<br />
points, it’s just as likely to select a moving<br />
object as the static background scene.<br />
Small movements can be dealt with by<br />
the software, so swaying trees don’t<br />
seem to cause too much of a problem.<br />
However, an object traversing<br />
the scene, such as a vehicle, person,<br />
or animal, can present too much<br />
of a problem. Boujou handles this<br />
<strong>com</strong>plication simply – to prevent<br />
these objects from being tracked
