Trying to understand output of 25 head pose estimator about pinto_model_zoo

[PINTO0309]

Have you tried the following? A working test code has already been committed. ssdlite_mobilenet_v2

Okey, I can see now that I was trying to use the Pose_Estimator in place of the Face_Detector.

Now, I tried to use the face detection models on Emgu.TF (C#) and I am having these problems:

If I load ssdlite_mobilenet_v2_face_300_integer_quant_with_postprocess.tflite on Emgu.TF.Lite it seems it points to the incorrect input tensor. Instead of pointing to normalized_input_image_tensor, it points to BoxPredictor_4/BoxEncodingPredictor/weights which is not good to use...

Then, I tried to use the PB model at 25_head_pose_estimation\01_float32\01_face_detector, but when I try to load it, it gives me this error:

Op type not registered 'TFLite_Detection_PostProcess' in binary running on DESKTOP-XXXXXXXX. Make sure the Op and Kernel are registered in the binary running in this process. Note that if you are loading a saved graph which used ops from tf.contrib, accessing (e.g.)

Also, keep in mind my knowledge of Python is very limited, I'm trying to use some of your models using C#.

TFLite_Detection_PostProcess is a custom OP for Tensorflow Lite. The derived version of Tensorflow Lite probably won't run. If you don't need a custom OP, use the Object Detection API to train and just generate a .pb file without specifying "--add_postprocessing_op=True".

Closed due to lack of progress.
