mobilenet-v2-1.0-224

Use Case and High-Level Description

mobilenet-v2-1.0-224 is one of MobileNet models, which are small, low-latency, low-power, and parameterized to meet the resource constraints of a variety of use cases. They can be used for classification, detection, embeddings, and segmentation like other popular large-scale models. For details, see the paper.

Input

Original Model

Image, name: input, shape: 1, 224, 224, 3, format: B, H, W, C, where:

  • B - batch size
  • H - image height
  • W - image width
  • C - number of channels

Expected color order: RGB. Mean values: [127.5, 127.5, 127.5], scale factor for each channel: 127.5.

Converted Model

Image, name: input, shape: 1, 224, 224, 3, format: B, H, W, C, where:

  • B - batch size
  • H - image height
  • W - image width
  • C - number of channels

Expected color order: BGR.

Output

Original Model

Name: MobilenetV2/Predictions/Reshape_1. Probabilities for all dataset classes in [0, 1] range (0 class is background).

Converted Model

Name: MobilenetV2/Predictions/Softmax. Probabilities for all dataset classes in [0, 1] range (0 class is background). Shape: 1, 1001, format: B, C, where:

  • B - batch size
  • C - vector of probabilities.

Download a Model and Convert it into Inference Engine Format

You can download models and if necessary convert them into Inference Engine format using the Model Downloader and other automation tools as shown in the examples below.

An example of using the Model Downloader:

omz_downloader --name <model_name>

An example of using the Model Converter:

omz_converter --name <model_name>
