IPNC DM368. About Katana filter parameter...

G.S.Lee
Intellectual 465 points

Dear all,

I'm developing IP camera with IPNC DM368 kit.

For Katana noise filter, I can't find any explained document about Katana noise filter.

Maybe, It seems spatial filter or kernel filter with macro block.

ipnc_rdk\av_capture\framework\alg\src\Alg_vnf.c file has gAlg_vnfPrm array for its parameter.

Where can I find document about katana parameter?

On the other side, TNF's 2 paramters can be found easily.

One is mixing or blending level. And another is drag rate.

Thanks.

    I can't find any document now.

    If I get some information, I will post it to here.

    I use IPNC_RDK_DM36x_v5.1.0.

    In file alg_vnf.c used filter settings KNF(Katana noise filter) and TNF(Temporal noise filter):

    Dear Vladimir,

    I saw your post and think you also have problem to understand parameters.

    In my application, katana filter has over filtering now.

    I need reducing filter effect to 50% from now.

    When I found correct usage of parameter, I will post to here.

    Hi G.S.Lee!

    I get strong effect from parameters:

    for KNF

    nsf_thr00, nsf_thr02, nsf_thr04, nsf_thr05;

    Get blur image.

    for TNF

    TNF_A0, TNF_TM;

    Get good frame, but I get motion effect in frame (TNF_A0 = 0, TNF_TM = 100).

    Thanks for Your reply.

    Dear Vladimir,
    Did you get KNF filter's documents?

    Hi Vladimir,

    Have you got any solution for motion effect on enabling TNF ?
    We are facing the same issue.
