Load Faster R-CNN Object Detection net with Tensorflow 2.5.0 and OpenCV 4.3 DNN package

  Now I want to use the OpenCV (4.3.0) dnn library from opencv's extra modules to load the net in my java environment. When executing "readNetFromTensorflow" I get some errors. Seems that you need to save your TF model into a "FrozenGraph" in order to be able to use it in openCV: https://github.com/opencv/opencv/issues/16879 https://github.com/opencv/opencv/issues/16582 https://github.com/opencv/opencv/issues/18005

  However for some reasons TF2 doesn't support the export to a frozen graph anymore. There are some workarounds: https://medium.com/@sebastingarcaacosta/how-to-export-a-tensorflow-2-x-keras-model-to-a-frozen-and-optimized-graph-39740846d9eb https://leimao.github.io/blog/Save-Load-Inference-From-TF2-Frozen-Graph/ https://github.com/tensorflow/models/blob/master/research/object_detection/export_inference_graph.py
