hy, i want to detect moving object in aerial video, the problem is camera also moving , so the background in the video is moving too. it's difficult to me to solve this problem, can anyone help me? here's my code until now

#include "stdafx.h"
#include "iostream"

BruteForceMatcher

hai im using opencv 2.4.3 , and i'm try to call BruteForceMatcher , but i have error

this is my code

}

and this is the error
