5.1 Element Descriptions
This section describes each element of the image analytic plugin in greater detail.
5.1.1 adtrans_classifier

The following pipeline translates the OpenVINO inference result using the classification type model into a human-
readable format.
gst-launch-1.0 videotestsrc ! advino model=classification.xml device=GPU !
adtrans_classifier class-num=1000 label=label.txt ! ximagesink
The following pipeline translates the TensorRT inference result using the classification type model into a human-
readable format.
gst-launch-1.0 videotestsrc ! adrt model=mobilenetv2.engine batch=1 scale=0.017 !
adtrans_classifier class-num=1000 label=labels.txt ! ximagesink
