Migrate to single opencv-wasm #145

Closed studentutu closed 4 months ago

studentutu commented 5 months ago

Good evening, I've tried many different ways to use open-cv with electron and other frameworks - and every time, opencv4node just breaks all of the sudden.

I've come to conclusion - it is better to use a pre-compiled wasm version, which is already done in a package - https://www.npmjs.com/package/opencv-web (it just needs to fix it's types)

Could you migrate the big api change done in this framework into a new opencvwasm4nodejs?

It will not have any issues with usage/installs that we currently have, and it will give you the satisfaction of finally making openCv whole again.

There are even docker files for opencv wasm build, the only thing missing are type support. Used https://github.com/CezaryDanielNowak/fast-opencv-wasm to build latest opencv 4.10 and it did a great work building it even on windows ( needed to change path for the docker run, but otherwise completly seemless build expirience)

Sadly - provided auto-generated types ( custom script which basicly dumps keys and adds comments on top) does not yield any good types.

@UrielCh Can you help with auto-generating types based on the sources, js and wasm file?

Hi,

I do not use the WASM version of OpenCV because it lacks many features, is slower, and does not support CUDA.

Currently, I am not using OpenCV for any active projects, as I need to find a real job before investing more time in open-source projects.

I'm currently working on some data conversion tools, LLM, and voice cloning API, so no computer vision right now.
