questions about cnf (chroma noise filter) #17
Comments
Do you mean this patent ? But I wonder that how we can distinguish whether we reduce the chrominance or luminance noise by these filters? |
Thanks but seems it's a temporal filter |
usually chroma noise is dealt on the UV plane of a image and luma noise is dealt on the Y plane |
I am wondering that which paper does the CNF(chroma noise filter) come from?patent is not the source paper of CNF |
I am confused whether cnf (chroma noise filter) works cause it uses a weird algorithm which i know, coming from a patent.Have you tried to figure out the effectiveness of chroma noise filter?thanks!
