This topic describes how to run the Hello Infer Classification sample application. The sample is simplified version of Image Classification Sample Async and developed with support of UNICODE. It demonstrates how to use the following Inference Engine API in applications:
There is also an API introduced to crop a ROI object and set it as input without additional memory re-allocation. To properly demonstrate this API, it is required to run several networks in pipeline which is out of scope of this sample. Please refer to Security Barrier Camera Demo, or Crossroad Camera Demo with an example of using of new crop ROI API.
Refer to Integrate the Inference Engine New Request API with Your Application for details.
NOTE: By default, Inference Engine samples and demos expect input with BGR channels order. If you trained your model to work with RGB order, you need to manually rearrange the default channels order in the sample or demo application or reconvert your model using the Model Optimizer tool with
--reverse_input_channelsargument specified. For more information about the argument, refer to When to Reverse Input Channels section of Converting a Model Using General Conversion Parameters.
NOTE: Before running the sample with a trained model, make sure the model is converted to the Inference Engine format (*.xml + *.bin) using the Model Optimizer tool.
The sample accepts models in ONNX format (.onnx) that do not require preprocessing.
You can do inference of an image using a trained AlexNet network on a GPU using the following command:
The application outputs top-10 inference results.
