Hello there, I'm new with openCV.

I have the following question regarding blobs detection:

I'd like to distinguish blobs when they are near. For example in the traffic sequence is possible tracking 2 or more cars(or pedestrian) as one unique blob. Until now I am tracking blobs using foreground technique and I correctly detect separated moving objects. When there are 2 objects attached my segmentator catch the 2 objects as one blob, instead of two.

You know if there techinque for separating blobs that are near? for example using histogram..

Thanks.

You may be able to separate them if they have been distinguished in some way, for example different color or gray scales. Another thing to consider will be a filter like Kalman that keeps track of their motion. Such filter will track them while the pedestrians move towards each other, lose them while they are merged, and track them again after they have been separated. You may have to play with some fine tuning on the filter.
