Algorithms behind noise reduction functions

Hi all,
on what algorithm are based the ippsFilterNoise functions?
In the code samples there are 3 examples of noise filters:
IPP_NR_EC, IPP_NR_RTA, IPP_NR_EPHM.
IPP_NR_EPHM implements the Ephraim-Malah noise suppressor algorithm.

The other two use directly the ippsFilterNoise_RTA and ippsFilterNoise_EC
but there are no references or mentions of an algorithm in the library
documentation...

Hi,

We are not explained algorithms of all the functions in the manual, but usage modes are presented in the IPP sample code. I hope this will help you to use it in your application.

ippsFilterNoise_RTA is very useful function to create Microsoft* Real time codec(MSRTA).

Regards,

Naveen Gv
