can anyone help, how to extract bounding box values from blob analysis in GMM method. thank you

i'm using GMM method to segment the moving objects and to detect object by using tld algorithm.

everything is okay but i need bounding box values from blob analysis..

finally i got values but when it is given as input to the tld algorithm , it shows error like bounding box is too small of invalid.

the problem is in the video stream i got 9 objects detects using GMM, when i try to retrieve bbox values it will retrieve 9*4=36 values, so i need to retrieve any ones's object bbox values, so please any one help with that... thank you
