vesuvius-ink-detection-cpp

ONNX C/C++ Runtime to detect ink in Vesuvius scrolls. Is a work in progress / not yet correct.

To export ONNX model from PyTorch:

1. Git clone https://github.com/younader/Vesuvius-First-Letters.
2. Edit "inference.py" after model.eval statement.

torch_input = torch.randn(1, 1, 32, 32) // Todo(kbostelmann): Use dynamic input shape?
onnx_program = torch.onnx.dynamo_export(model, torch_input)
onnx_program.save("my_image_classifier.onnx")

3. Install python packages and run script.

You must run on Linux because dynamo is not supported on Windows. You must also edit "i3dall.py" or an unsupported class list error is thrown:

       if self.forward_features:

            x = self._modules['Conv3d_2c_3x3'](x)
            features.append(x)

            x = self._modules['Mixed_3b'](x)

            x = self._modules['Mixed_4e'](x)
            x = self._modules['Mixed_4f'](x)
            features.append(x)

            x = self._modules['Mixed_5b'](x)
            x = self._modules['Mixed_5c'](x)
            features.append(x)
            return features

Todo

• Fix data loader to fill inputs from many layer slices (batch size ???)
• Review gaussian filter and scale factor in predictions.
