| Sep 29, 2015 at 20:18 | comment | added | Kametrixom | If you really want good performance you should incooperate Accelerate if possible (Check out Surge for a Swift-y interface). If you want even better performance, you can use Metal, OpenCL or write your own image filter kernel with CoreImage Kernel. These all use the GPU instead of the CPU. I'd go for Metal or Accelerate, very nice to use in comparison to OpenCL and CI Kernels. | |
