Paint wall

[sangampandey]

do one single item I have to play around react-native-opencv3-tests to see how things work in this library.

I have to achieve something like this https://sushanta1991.blogspot.com/2021/09/how-to-paint-wall-using-opencv-in-unity.html but Its very difficult with react-native-opencv3. I am not saying the library doesn't have potential but I have to try 10 things or dig through a lot to find a solution.

Any one faced similar issue and have potential solution?

I also tried this library but it's not very good. So for image processing, we used C++ and vision camera frame processor.

I recommend C++ for better results, crossplatform and performance.

How did you build and link opencv with c++ in the frame processor?

How did you build and link opencv with c++ in the frame processor?

• I call my C++ code on the React Native side using JSI.
• I wrote a custom FrameProcessorPlugin to convert frame values to cv::Mat type.
• In this plugin, I call the init method for the C++ side, which tells me if the image is in the format I want.
• If everything is ok, I now call the C++ method.

Basicly that look like this;

const process = useFrameProcessor(frame => {
    'worklet';
    const result = opticReaderProcess(frame)
    if (result.ok) {
        const runResult = OpticReaderJsiModule.run(result.mat, options)
        // blabla
    }
})

I'm thinking of opening a repo about it. It can be a guide for those who want to use OpenCV and C++.
