OpenCV Stitching example (Stitcher class, Panorama)

Image size of origin is 320*240. 

Processing time is 30.96 second took.

    The result of stitching

The result is pretty good. but, processing time is too much takes.

My computer spec is that.. (This is vmware system. The main system is mac book air 2013, i7 8bg)

The source code is very easy.
I think if we use stitching algorithm in realtime, we should be programing by GPU.

 if (Stitcher::OK == status) 
  imshow("Stitching Result",rImg);
  printf("Stitching fail.");




N image, realtime stitching.
source code:
how to work:

2 image stitching.

I have decided to sell source code ^^
If you have interest, go to here, you can buy source code.
Thank you very much!!
