Getting Started with OpenCL on Android

Pradeep Android, JAVA, OpenCL 10 Comments

Mobile devices are carving their niche into the world of computing with more processing power day by day. GPUs on mobile devices have been around for a while, but using them for accelerating computation is still quite new. Until recently, the only way to access the GPU was through OpenGL. Around december 2008, Khronos released OpenCL, a generic API for accelerating non-graphics tasks. OpenCL enables us to take advantage of acceleration hardware. Since it is an open standard, many hardware vendors provide support on their devices. With the recent release of Adreno and Mali SDKs, you can now run OpenCL code on mobile GPUs. Today's post is going to be about how to do image processing on camera feed on ...

Fast Computer Vision with OpenCV and ArrayFire

Update:  While the post below discusses LibJacket (no longer a product), you can do the same thing in the newer, but different, ArrayFire library.  Improved performance benchmarks and a simpler API are the results of moving from LibJacket to ArrayFire. Mcclanahoochie just posted some code and instructions for pairing OpenCV with LibJacket to get accelerated computer vision.  You can do really fast image processing on video cam feeds too, see picture below: Really cool stuff.  Computer vision is really hot with applications emerging in defense, radiology, games, automotive, and other consumer applications. Computer vision algorithms like these are also going mobile.  For instance, we have started to build LibJacket for Mobile applications, which runs on Tegra, PowerVR, and other mobile ...
