Why [am] i getting this error in both center1 and center2 and any way to prevent this error i have to represent this to my external

Check the sizes of the variables face1 and face2

What I expected. So, the object detector logic returned nothing recognizable. Your mission, should you choose to accept, is to investigate "why"....we've no way to know from the info posted.

No face detected so I guess there is either no one in the picture, or, my guess, he's wearing his ninja outfit.

Cascade object detection relies on patterns that are not certain to be present even if there is s face in the input images, and there is no certainty that the input has a face at all. The code is wrong for not testing to be sure that a face was detected. The code is also wrong for the case where more than one face is detected.
