Hello! I’m actually using PeopleNet and from the cfg file I can see there’s a “minBoxes” parameter. I wanted to know if I can get minBoxes from one inference, like we can normally get confidence, height, width, etc.,and if so, which plugin should I use?
This is done with Python, but if this can be achieve with C/C++ it’s no problem.

Thanks in advance!

Please check below code about minBoxes usage in
sources/libs/nvdsinfer/nvdsinfer_context_impl_output_parsing.cpp::DetectPostprocessor::clusterAndFillDetectionOutputDBSCAN, just list one case, you can search the code for other class type. as for detected number of bbox of objects, did you mean detected number of bbox for specific object, let’s say person, car or bycicle?
/* Cluster together rectangles with similar locations and sizes
* since these rectangles might represent the same object using
* DBSCAN. */
if (detectionParams.minBoxes > 0) {
m_DBScanHandle.get(), &clusteringParams, objArray, &numObjects);
[detectionParams](const NvDsInferObjectDetectionInfo& obj)
{ return (obj.detectionConfidence <
? true : false;}),m_PerClassObjectList[c].end());
totalObjects += m_PerClassObjectList[c].size();
