Post idea: running neural networks in Pyodide with OpenCV

[ryanking13]

Recently we added OpenCV to Pyodide. While testing OpenCV, I was able to run Pytorch neural network (converted to ONNX) in Pyodide using OpenCV DNN modules, though it is inference only and of course very slow (no GPU).

I would like to share some ideas about it, which also include some examples of handling images and dealing with the file system.

You can test it here: https://ryanking13.github.io/style-transfer-pyodide/

Very nice demo, looking forward to reading your post!

On the demo page, you might want to put a sentence mentioning OpenCV and ONNX (or put it in the title). And also enable re-sizing by default, otherwise it's will take a long time if the user uploads some high res image.

Personal opinion, and feel free to ignore, but it would be nice if the post also answered the question:

There is opencv-wasm and ONNX which work already in the browser, so why do we need Pyodide to do this?
