Can I modify resizer coefficients on DM36x?

Hi, all

In my application, I hope to implement image resize by dropping some pixels.
The resize module seems to implement it by a FIR filter.  Several years I read it
in one document. But now I can't find such information in the documents of DM36x.
If I can configure filter coefficients, it will be easy to do it.
I am not clear whether I can set filter coefficients.

Thanks in advance.

Best Regards

    Hi, all

    I have searched the forum with the keyword(resizer and coefficient). It seems that filter coefficients of resizer module
    on DM6437 and DM64x can be modified by the users. But I haven't found such information on the data sheet of DM365. So I am
    not sure about that. Do these processors use the same VPSS module? If so, the filter coefficients of resizer module on
    DM365 should be modified by users. Where can I find such information? Which data structure or interface should I use to do that?
    Thanks for your help.

    Regards
