Non-local means denoise filter, drop-in replacement of the venerable KNLMeansCL, but without the OpenCL dependency (CPU only).

x86 and arm are supported.

Usage

Prototype:

core.nlm_ispc.NLMeans(clip clip[, int d = 1, int a = 2, int s = 4, float h = 1.2, string channels = "AUTO", int wmode = 0, float wref = 1.0, clip rclip = None])

Compilation

ISPC is required.
