Hello TI experts,
I want to disable the NSF4 plugin in TDA4, I changed the "Noise Filter 4 enbale" to "OFF", then I process and export it in DCC, but I didn't see any change in the image of the camera afer I update the bin file to TDA4.
And the image also didn't change when I have complied the xml file into the SDK.
Here is the xml file of the NSF4 plugin:
<?xml version="1.0" encoding="utf-8"?>

Is the noise reduction srength too low? Or is it the wrong way for me to disable NSF4?
