Preprocess embossed datamatrix

Question

I need to read data matrices which are embossed into metal stripes. For this I need to preprocess the video stream or pictures in order to have common data matrix scanner SDKs scan that code.

Is there a common way or technique to preprocess this kind of embossed code or text? One thing making this harder is the fact that the code has to be readable from both sides, embossed in and out.

Answering my own question:

We found a very nice performing smartphone-only solution which works out of the box with such hard-to-read codes. It also works reliable and very fast in a warehouse environment.
