accuracy problem using myriad

hi

I tried to implement face recognition using openvino with MYRIAD plugin .Below zip file has complete source which i implemented using the reference of

https://github.com/davidsandberg/facenet and https://github.com/kuberlab/facenet i executed using 

20170512-110547 model

ubuntu 16.04

openvino 2019.1.144

Face detection was good but with face recognition i'm not getting proper result like mismatches and least accuracy .

how can i increase my accuracy ,i tried with passing scale value mean values .I need everything should run on NCS2 stick not on host machine .could u help me with this.

Dear kvgr, deepika,

As we have discussed before, you are likely not telling Model Optimizer about the pre-processing which Facenet does and that is why you're experiencing accuracy issues. Model Optimizer cannot know about this pre-processing. The person who builds the model must know the details about image pre-processing.

Please carefully study the following online resources to find out more about Facenet pre-processing:

Hope it helps,

Dear kvgr, deepika,

I found your other thread regarding Facenet accuracy issue and it seems that for MYRIAD devices:

The only solution is to train the model on Inception resnet v2 or to use compute stick myriad 1 until intel allow support for Incpetoin resnet v1 on new myriad devices.

Inception resnet v1 is not supported on NCS2. I have filed a feature request for this actually.

Thanks for sharing with the OpenVino community and I appreciate your patience !

Dear kvgr, deepika,

How about downloading it from the Model Optimizer Tensorflow Supported List ?

Thanks,

Shubha
