-Sometimes a single image can't capture it all. Here you will learn how to join
-more images together to create a large pano. Doesn't matter if you want to
-create a photo panorama or you want to stitch scans.

-
-    *Languages:* C++
-
-    *Compatibility:* \>= OpenCV 3.2
-
-    *Author:* Jiri Horner
-
-    You will use high level stitching api to create a photo panorama. You will
-    learn about Stitcher class and its configurations.
