three cameras performance

January 30, 2007 | 7:56 pm

Three cameras are connected but every so often the picture freezes. Then it continues but always not really living up to a good mix. We have an altivec optimisation, does that improve on a patch with three live cams?
I got a G5 with two 2.5 GHZ processors. The activity window shows 45% used on CPU power. It seems to appear like an optimisation problem. Anyone out there with some experiences about this topic?

cheers

The following patent is a bit scary for those using video tracking in
interactive installations using Jitter.

The patent for Video Gesture Control (VGC) technology contains wide,
sweeping claims. It was issued back in 1996 and is owned by Gesturetek.
Gesturetek’s website states, "This [patent] covers all applications
where a user appears on-screen and interacts with computer objects or
icons". They also licensed the VGC technology to Sony for the EyeToy.

Anyone else looked into this?? Does this mean that if one were to use
jit.3m or any jit.cv object to control the movement of something on
screen, that would be infringement?

To view the patent, do a Google Patent search for "Video image based
control system" at

if it is infringement, i imagine that first they would have to sue you for
it to be a problem. there are so many instances of tracking, i find it
unlikely. what about OpenCV? Eyesweb? SoftVNS? etc…

now if you were to include the technology in a mass-produced product, then
they’d have something to sue :)
