I am much impressed to watch the performance boost achieved by enabling the tegra optimization (https://play.google.com/store/apps/details?id=org.opencv.imgdemo). But I was wondering how can I do that in my code. I could not find any helpful documentation on how to utilize tegra power in the opencv website. Can anyone please help me on this?
The only thing you should do, is to use Android OpenCV Manager. On a Tegra 3 device it will provide your application with optimized version of OpenCV. These are dynamic libraries with API identical to the default version of OpenCV, but with a set of optimizations enabled. Corresponding packages are already published to Google Play market, so you can install your application on a Tegra 3 device and see if it gets performance improvement.
The list of optimized functions is available here: http://docs.opencv.org/opencv2refman-tegra.pdf, check Chapter 17, "TEGRA-POWERED COMPUTER VISION". Please note that not 100% of API was optimized, so probably your bottleneck will not disappear... In such a case you can submit a feature request on the http://code.opencv.org.
OpenCV for Tegra is also included into the NVIDIA's Tegra Android Development Pack.
And I suggest you to wait for the final OpenCV 2.4.3 release, because it suggests much better experience for end users. I mean significantly reduced number of clicks.
