Hi.

How fast motion compared to ZM?

Regards.

OpenX seriously rocks, I powered about ~1.5M ad impressions per day with phpAdsNew (it's ancestor) without any major issues.

It scales quite well from small sites to larger ones.

Hi.

IMHO, there are already 2 good directions which could be reused:

1) Continuing the work on Mor's analyzer (optimizing it etc...).
2) Adapting Motion analyzer.

These both has self-training features AFAIK, so the overall work won't be as necessary as large.

Hi.

This is interesting - in fact I suggested about a year ago of looking at motion as the motion detection replacement.

Perhaps motion could be put to a separate module, and enabled by users?

Hi. I have a performance question: If "With this patch, zma is now using less CPU than zmc, and I'm processing 45 fps on a 1.6GHz CPU @ ~ 75% CPU. ", meaning analysis now actually takes less CPU then capturing. How it's possible that Tim still gets these results? "The load is just about the same as ...

Hi. I was curios about the matter, so I checked the source code a bit. The only spot I noticed the timestamp value being used is in zm_mpeg.cpp file, in the EncodeFrame function: if ( add_timestamp ) ost->pts.val = timestamp; According to what I seen, this ost->pts.val nor ost->pts is never used any...

What ZM_MPEG_TIMED_FRAMES actually does?

Hi. Any idea what this option actually does, on streaming set to high? I tried several times with and without it, and the result seems the same. The help says "...This means that where the frame rate varies, for instance around an alarm, the stream will still maintain it's 'real' timing." Any idea w...

Hi. Updated patch at http://www.dgmo.org/zoneminder-1.23.3-motion-4.diff This has higher thresholds, and much, much lower CPU usage. (Less than half what was previously using). Just for future reference; calculations are free, accessing memory is expensive. time in ::Blend dropped by 30% switching f...

Hi. I think that by object removal/placement detection, SyRenity meant: For a museum an alarm could be generated if a painting was removed for more than X amount of time, but not if someone simply walks past it and obscures it. For an airport, an alarm could be generated it a suitcase (bomb) was add...

Hi.

Try this thread for improved motion detection mechanism:

It should be much more accurate (though I didn't have the time to test it myself yet).

Hi.

This image was impressive!

I presume, some more advanced functions like object removal and placement detections could be developed with this approach? Because you already have the ongoing "state" of the background, and can detect whether something was added or removed?

Hi.
mor wrote: It would probably be worth just adding decimation as a setting (2x, 4x or 8x decimation). I have a look at this when I start doing code optimization.
It's a good idea, and would allow people to decide for themselves whether they prefer speed or accuracy.

Cordel, are you sure about the openCV dependency on FFMPEG?

AFAIK, if only plain images used (as here in ZM) it should be ok.

Hi. Something that might interest you guys is the work of Andrew Kirillov: http://www.codeproject.com/KB/audio-video/Motion_Detection.aspx His work is done in c# but the principals might be useful. Indeed, I even posted about this a year ago here in forums. His 3rd method ( http://www.codeproject.co...
