Using OpenCL™ 2.0 Read-Write Images

While Image convolution is not as effective with the new Read-Write images functionality, any image processing technique that needs be done in place may benefit from the Read-Write images. One example of a process that could be used effectively is image composition. In OpenCL 1.2 and earlier, images were qualified with the “__read_only” and __write_only” qualifiers. In the OpenCL 2.0, images can...

Intro to Device Side AVC Motion Estimation

This article introduces the new device-side h.264/Advanced Video Coding (AVC) motion estimation extensions for OpenCL* available for Intel Processor Graphics GPUs. Video motion estimation is a powerful feature which can enable new ways of thinking about many algorithms for video codecs and computer vision. The search for most representative motion vector, which is computationally expensive if...
