Hi I am trying to add gaussian noise to CSI-2 GStreamer Camera Pipeline with OpenCV. Here is my approach: #include <opencv2/cudafilters.hpp> #include <opencv2/cudaimgproc.hpp> #include <opencv2/cudaarithm.hpp> #include <opencv2/opencv.hpp> #include <opencv2/highgui.hpp> using namespace cv; using na…

Hi, We don’t have much experience about using the function. Not sure if it is possible to apply the effect to GpuMat directly. Please go to OpenCV forum to get further suggestion: https://forum.opencv.org/

Hi DaneLLL, Instead of applying Gaussian Blur Filter to the video as your post described, I actually want to manually add Gaussian noise to the video in real-time. I am assuming the lagging is caused by randn(h_noise,m,sigma) Since it uses random seed from CPU to generate Gaussian distribution in…

Hi, There is concern of processing BGR data on Jetson platforms. Please check the discussion in [Gstreamer] nvvidconv, BGR as INPUT - #2 by DaneLLL So we would suggest process RGBA data. Performance will be better by eliminating RGBA <-> BGR conversion. But if it does not fit your use-case, you m…

DeneLLL, I do not think BGRA<->BGR conversion is the bottleneck in my case. It is generating gaussian random number on CPU then copy to GPU slows the algorithm in every loop. My question can actually turn into HOW to generate Gaussian Radom Number directly on GPU as GpuMat.

Hi,
Please refer to this sample:
