Median Filter

Download for Windows* Download for Linux* Download Documentation

Features / Description

The sample demonstrates how to implement efficient median filter with OpenCL™ standard. This implementation relies on auto-vectorization performed by OpenCL compiler. The kernel code 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.
