How to Generate a Heatmap Using OpenVINO™?

Can a heatmap generation technique like layer-wise relevance propagation or Grad-CAM be implemented using OpenVINO™?

Activation maps can be used to visualize the decision-making.

In order to calculate Class Activation Maps in OpenVINO™, is necessary to:

• Access the output feature maps of the last layer and the corresponding weights.

  Note	This can be done through the CNNNetwork: addOutput() function call when initializing the network.

After running the inference, calculate the weighted sum of the weights with the feature maps and use this to generate the visualization.
