Hi I want to use Exposure Compensator class standalone. Does anyone knows the meaning following input arguments?

compensator->feed(corners, images, masks);

For example when I was stitching two images I got two corners:

Corner #0 : [-270, 325]

Corner #1 : [-86, 327]

How can the top-left conrner be a negative value? What's the meaning?

Thanks!

Finally I make it clear. It's just the top-left corner of the image in the BIG map. Since this class is especially for images stitching, after registration, the warped images can have different positions.

Simply use for two ready (warped) images, giving the two corners [0, 0] is just fine.

  • Could you explain further? Do you have any sample code for it? [Here](http://stackoverflow.com/questions/13978689/balancing-contrast-and-brightness-between-stitched-images) is another similar question also requiring more details. Cheers. – Sergio Basurco Oct 09 '13 at 10:47
