Features / Description
The sample demonstrates how to implement efficient median filter with OpenCL*. This implementation relies on auto-vectorization performed by Intel® SDK for OpenCL* Applications compiler. This kernel code effectively minimizes number of color buffer accesses, removes synchronization points, and uses data-level parallelism.
This sample demonstrates a CPU-optimized implementation of 2D image median filtration, showing how to:
- Implement calculation kernels using OpenCL* C99
- Parallelize the kernels by running several work-groups in parallel
- Organize host-device data exchange with final image storage on the hard drive.
Supported Devices: CPU, Intel® HD Graphics 4000/2500
Complexity level: Novice
