OpenCV-Color-Detection

This program uses OpenCV to process CameraX information.

Setting

MainActivity Path : /app/src/main/java/com/example/opencvcolordetection/

imageAnalysis = new ImageAnalysis.Builder().setTargetResolution(new Size(176, 144))
                            .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST).build();

At setTargetResolution(new Size(x, y)), set the resolution.

    private class MyImageAnalyzer implements ImageAnalysis.Analyzer {
        private Mat matPrevious = null;

        @Override
        public void analyze(@NonNull ImageProxy image) {

            Mat matOrg = getMatFromImage(image);

            Mat mat = fixMatRotation(matOrg);

            if (matPrevious == null) matPrevious = mat;
            matPrevious = mat;

            Bitmap bitmap = Bitmap.createBitmap(matPrevious.cols(), matPrevious.rows(), Bitmap.Config.ARGB_8888);
            Utils.matToBitmap(matPrevious, bitmap);
            
            //Describe the process you want to process in this class

            image.close();
        }

In this case, if you continue to take the average of the RGB, you can see it in the log.

Difference

Processing speed has been increased by cutting the library files by about one-third.
