Uniqueness with PVA+NVENC+VIC backend for Stereo Disparity

For my use case with stereo disparity, the parameter “Uniqueness” is very important. I see here that uniqueness is a parameter that can be tuned, but that it is “only applicable when using CUDA backend.”. Are there any plans to add this parameter to the PVA+NVENC+VIC backend as well?

Hi,

NVENC is a hardware-based estimation that doesn’t have such a feature.

Thanks.

Ok, I just recently found this thread here: VPI Stereo Disparity background (sky) noise - #19 by stbnhan
Is the uniqueness feature you mentioned here referring to only the CUDA backend? You mentioned it would be added in the next Jetpack major release (this was a few months ago)

Hi,

Yes, uniqueness is only available in the CUDA backend.
You can also find this in our document below:

https://docs.nvidia.com/vpi/group__VPI__StereoDisparityEstimator.html#a31540c04c404e186d205708660eba061

Uniqueness ratio, in [0, 1] range, … It’s only applicable when using CUDA backend.

Thanks.
