Research direction

Start at the addon entry point handling args[0]->ToObject() and review how the repository's Node.js C++ addon examples pass image buffers into native code. The issue does not identify a file, test, or acceptance criteria; clarify the expected buffer representation and cv Mat conversion before defining what done means.

Written by the indexing model from the issue text.

Description

I transfer the image buffer data from js to cpp, using Local value = args[0]->ToObject();
But after that I don't know how to use the data in cpp.
I hope to convert that to cv Mat type.
If someone know about it, please give me an advice.
Thank you.
