| Post subject: | traffic counting |
Hi i´m using EyesWeb for the first time... Im working on a traffic counting. We have a video stream of a street.What we have to do is to make a spreadsheet with : number of cars, number of trucks ( both per minute or another intervall. I think we have to work with blob extraktion... But how can u make an integer counter whenever a new blob is moving through the screen? Save this counter with a timestamp,increase it with each new blob, begin a new one after 60 seconds... And we have to filter the blobs... Only the bigger ones ( cars,not passengers) should be countet. Sry for bad english, greetings Jan Hackenberg |

The SelectMultipleTrackedBlobs let you choose the first N (where N is user defined) blobs, ordering them by size (area). It also extract the label of the blob; since the label changes when the blob is replaced by a new one, you can build a patch basing on this to develop your tarffic counter application. Paolo |
