3 reasons:
1) We found that of the various methods available for grabbing and decoding an image out of the camera buffer, this was the fastest.
2) It let us minimize memory allocation and buffer copying in the most performance-critical part of the code.
3) We already had a working C++ vision prototype for the Tegra, so all we had to do was copy and paste.
