I am trying to build a face recognition pipeline with deepstream. For detection, I am using redaction-app with the help of this article redaction-retinanet but I am not able to handle landmarks point. If i try to add any parameter to NvDsInferObjectDetectionInfo(nvdsinfer.h) i am getting segmentati…

Actually, I had added a filed in NvDsInferObjectDetectionInfo like what you did and access the filed in post process parser and it can work well. So I guess there must be something wrong in your code or setup. For how to check backtrace of the core dump file, pls refer linux - How do I analyze a pro…

No i am trying to run deepstream app. Its almost similar to post mentioned. Just instead of retinanet i am using some other model in which in output layer i have bounding box and landmarks point. I can run without landmark.

My code does not reach to the callback function which deepstream passe to gstream pipeline. If i add any parameter to NvDsInferObjectDetectionInfo.I get segmentation fault. I am getting confidence value . My aim is to associate landmark array or 10 int/float value to each box.

Which callback? Are you referring the post process parser? Could you share your code with us?

Yes post process parser. My parser runs ok. Yes i can share You want to check parser code or Nvdsinfer code?

Share all what you had changed, I will try to setup locally, you can send me a private msg if you have any concern.

i am not able to upload code file here is I have changed to nvdsinfer.h /** Holds information about one parsed object from detector’s output.*/ typedef struct { /* ID of the class to which the object belongs. */ unsigned int classId; /** Horizontal offset of the bounding box shape for the ob…

Thanks, Where did you access the landmarks filed, we cannot help to debug if you don’t share me with your change. Also you can check the backtrace of core dump file to check where the app crash?

I was using it in my custom parser function. But there is not any difference even if i comment that code. I gets segemtation fault after my custom parser return and before post parser callback. I can get “All Done” log. Here is my custom parser code. /** Copyright (c) 2017-2018, NVIDIA CORPOR…

It should work, could you refer the change in nvinfer is not populating 'confidence' field in NvDsObjectMeta (DS 4.0) - #20 by CJR firstly, and share your code with us if you still have issues.
