R36.4.3 libnvisppg.so version question

[Cherry123]

Hi NV experts,

We found that in the JP6.1 version, after enabling noise reduction, the overall image details were severely lost. After using the libnvisppg.so provided by you, the details improved significantly, but the overall noise became much larger and the edges became overly sharp. Could you please tell us if there are other versions of this libnvisppg.so or if there are any updates? The attachment is the so file we are currently using.Thank you!

Looking forward to your reply.

update JP6.2 Version

[Cherry123]

the left image is the new libnvisppg.so ,the right image is the old so file, the camera_overrides.isp use the same one.

Restore to native libnvisppg.so and add below to camera_overrides.isp to verify by JP6.2

demosaic.v6.enableDmx = true;

Hi NV experts

 After reverting to the previous libnvisppg.so as you suggested and adding "demosaic.v6.enableDmx = true;" in the ISP parameter file, the image quality has become even more blurry.

Hello @1465982276,

Hope everything is going great !

We faced a similar issue while supporting one of our clients with their project.
We were able to fix the camera blur problem with the solution from this forum.

Hope you find it useful.

Hi NV experts,

We tried replacing the libnvisppg.so file, which effectively improved the image blurriness issue. However, at the same time, it introduced a lot of persistent noise that cannot be removed. These noise artifacts are not reducible through current settings or adjustments.

Add below for bad pixel.

badPixelCorrection.v6[0].Or2Mode = 1;

[1465982276]

Hi NV experts，we have implemented the badPixelCorrection.v6[0].Or2Mode = 1 setting you provided, but we haven’t observed any improvement regarding the defective pixels in the image. Could you please advise if there are any other solutions or recommendations available?

[ShaneCCC]

Please try below.

badPixelCorrection.v6[0].Or2Mode = 1;
badPixelCorrection.v6[0].Or2NoisePorfileEnabled = TRUE;
badPixelCorrection.v6[0].Or2StatsEnabled = TRUE;

[1465982276]

Hi NV experts
Today I tried the new solution you provided, but there is still no noticeable improvement in the issue. Are there any version requirements for the following settings?

badPixelCorrection.v6[0].Or2Mode = 1;
badPixelCorrection.v6[0].Or2NoiseProfileEnabled = TRUE;
badPixelCorrection.v6[0].Or2StatsEnabled = TRUE;

Currently, I am using JP6.2.

[ShaneCCC]

Make sure the camera_overrides.isp is applied.

Maybe have below command to check again.

sudo chmod 644 camera_overrides.isp

[Cherry123]

Hi ShaneCCC,

We confirmed that the camera_overrides.isp was applied correctly, and we also modified the 644 permissions. However, it seems that after the JP6.2 update of libnvippg.so, the black noise became more obvious. Could you please tell me if the JP6.2 version has changed the noise reduction algorithm compared to JP5.1.2?

[ShaneCCC]

Bad pixel correct still have problem to enable on Orin in current release.

We are working to fix it.

[1465982276]

Hi NV experts,

We’re currently observing noticeable black noise in our images under both bright and dark lighting conditions, which is significantly degrading overall image quality.

Could you kindly advise on potential approaches to mitigate this issue—preferably without compromising the current level of image sharpness? We’ve already noticed that the image exhibits a somewhat heavy smearing or over-smoothed appearance, so preserving detail clarity is particularly important.

Thank you very much for your support!
