I'm studying OpenCV and running examples on an Nvidia Jetson Tk1 dev board. It has the Tegra K1 SoC. Nvidia's SDK comes with its own distr of OpenCV4Tegra. It is actually 2.4.10 with, as I understand, some additions from Nvidia.

So what's the difference between standard OpenCV 2.4.10 and the OpenCV4Tegra?

Thank you.

There is no different functionality, only extra functions that are optimized for the architecture, so that some functions have a speed-up advantage, however there is no wrap up list with what exactly. So if it comes to functionality available, there is no difference between builds.

Steven, may I ask you for a little bit more details on "optimized for architecture"? Does it mean optimized for CPU or for the GPU? Here's the Nvidia's list http://docs.nvidia.com/gameworks/inde... and there are no words about optimizations for GPU.. I'm a bit confused. Thanks.

The following is a list of functions that are specifically optimized for Tegra --> grabbed from the website :D
