I want to do basic frame difference like this :
diff = current frame - previous frame
is this correct way to so this ? I"m not sure how to get current and next frame
#include <highgui.h>
#include <iostream>
using namespace cv;
int main()
{
VideoCapture cap("Camouflage/b%05d.bmp");
if(!cap.isOpened())
{
std::cout<<"failed to open image sequence";
return 1;
}
char c;
Mat frame1, frame2, frame3;
namedWindow("Original Frames",1);
namedWindow("Frame Difference",1);
while(1)
{
cap>>frame1;
if(frame1.empty())
{
std::cout<<"Frame1Message->End of sequence"<<std::endl;
break;
}
cap>>frame2;
if(frame2.empty())
{
std::cout<<"Frame2Message->End of sequence"<<std::endl;
break;
}
frame3=frame1.clone();
frame3=frame3-frame2;
imshow("Frame Difference",frame3);
c=waitKey(90);
if(c==27)
break;
imshow("Original Frames",frame1);
c=waitKey(90);
if(c==27)
break;
}
}
