It used to be that portable OpenCL applications required shipping source code for the parallel kernels with the application. In this way, the kernel source code could be compiled for any device at any time in the future. Bad news from an IP protection point of view! The alternative was to pre-compile the kernels thus bloating applications and limiting the devices the OpenCL … [Read more...]

Machine-Learning At Siggraph Changes the Weather and Other Aspects of an Image
More machine-learning at Siggraph. A paper describing a machine-learning method being developed a Brown University enables users to instantly change the weather, time of day, season, or other features in outdoor photos with simple text commands. Changing the weather in a photo involves much more than simply turning a blue sky gray. There are subtle changes in color and … [Read more...]
Microsoft Shows Hyper-Lapse Video Tech for Smooth and Interesting Action Videos for the Masses
At Siggraph 2014, Microsoft is demonstrating a method to convert first-person videos, (e.g. captured with a helmet camera during activities such as rock climbing or bicycling) into hyper-lapse videos that effectively merge time-lapse segments of the video into a single video that looks like it was created with a smoothly moving camera. The results look great and are clearly … [Read more...]
Paper Compares AMD, NVIDIA, Intel Xeon Phi CFD Turbulent Flow Mesh Performance Using OpenMP and OpenCL
