The NVIDIA CUDA Deep Neural Network library (cuDNN) is a GPU-accelerated library of primitives for deep neural networks. Deep learning developers and researchers worldwide rely on the highly optimized routines in cuDNN so they can focus their efforts on designing and training neural network models rather than spending time on low-level performance tuning.

This is a version of OpenCV that NVIDIA optimized specifically for the Tegra platform family. It is available for Linux for Tegra, Android, and Vibrante (Embedded Linux) operating systems. It contains Tegra-specific optimizations that enable it to often run several times faster than the OpenCV for Android implementation.
