cvFastNlMeansDenoising

Basic

Perform image denoising using Non-local Means Denoising algorithm.

	Name	Type	Range	Description
	inImage	Image		Input image
	inFilterStrength	RealArray		Parameter regulating filter strength. Big h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise.
	inTemplateWindowSize	Integer	1 -	Size in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly.
	inSearchWindowSize	Integer	1 -	Size in pixels of the template patch that is used to compute weights. Should be odd.
	outResult	Image
