     :param objects: Vector of rectangles where each rectangle contains the detected object.
 
-    :param weights: Vector of weights of the corresponding objects. Weight is the number of neighboring positively classified rectangles that were joined into one object.
-
     :param scaleFactor: Parameter specifying how much the image size is reduced at each image scale.
 
     :param minNeighbors: Parameter specifying how many neighbors each candidate rectangle should have to retain it.
