Sub scene movement searching

tibby · Post by **tibby** » Mon Nov 28, 2005 1:55 am

Is there a way to zoom in to a section of a scene and seek through the captured footage until we reach a reasonable amount of movement there?

For example, some footage of a bench top having a laptop. Can we put a bounding rect around the laptop & fast forward till about the time it disappeared?

You can not put a modetect zone and search for movement in that area on captured files yet. I think the recent additions that Phil put in 1.21.4 might be to support just that in the future. I do know that it's in the requested features list. If you have a zone set to record and you know a time frame (the spacific event) you might want to convert it to mpeg (need ffmpeg installed) and use something like WMP to forward through the video. That would be the quickest way I can think of other than sitting and watching the whole clip.

This is on the 'to do' list but not yet available. I am making some changes to the zones that will make it easier to implement in the future.

Phil could these changes you make involve a means of my app passing the info needed for this too. Id love to have it (when it happens) and be able to search from my app, but im thinking the best way is to get the server to check its images rather than medownload tonnes of events and motion detect them at the client?

Yes, probably. I haven't thought enough about it to really figure it out yet but I expect it will a case of getting zma to run in a special mode with temporary zones. Or something!

thats what i thought create a new stream from the images, make a zone in the cordinates specified then run all the images through it, i suppose it will need another db to keep track of all the images from that event with motion in that particular zone, i was thinking i could pass co-ordinates and size sensitity info etc to you and you would do all the hard work lol

Yes, I epxect this will be the case. I don't know whether the results would go in the Db as events or not. I suspect not, and that they will either just be reported as event and frame ranges of interest or put in a special temporary event table and then they could optionally be converted to events. The idea of having multiple events all covering the same timespan is a little bit worrying!

yeah the temp db looks best maybe just the last search and on a new search the db is wiped?
