try this solution with your clip result which is getting in the segmentation result from ML kit.

@ColorInt
    private Bitmap maskColorsFromByteBuffer(ByteBuffer byteBuffer, int maskWidth, int maskHeight) {
        @ColorInt int[] colors = new int[maskWidth * maskHeight];
        for (int i = 0; i < maskWidth * maskHeight; i++) {
            float backgroundLikelihood = 1 - byteBuffer.getFloat();
            if (backgroundLikelihood > 0.9) {
                colors[i] = Color.GREEN;
            } else if (backgroundLikelihood > 0.2) {
                // Linear interpolation to make sure when backgroundLikelihood is 0.2, the alpha is 0 and
                // when backgroundLikelihood is 0.9, the alpha is 128.
                // +0.5 to round the float value to the nearest int.
                int alpha = (int) (182.9 * backgroundLikelihood - 36.6 + 0.5);
                colors[i] = Color.argb(alpha, 0, 255, 0);
            }
        }


        Bitmap bitmap = Bitmap.createBitmap(maskWidth, maskHeight, this.bitmap.getConfig());
        Paint p = new Paint(Paint.ANTI_ALIAS_FLAG);
        Canvas canvas = new Canvas(bitmap);
        canvas.drawBitmap(this.bitmap, 0, 0, p);
        p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_OUT));
        canvas.drawBitmap(Bitmap.createBitmap(colors, maskWidth, maskHeight, this.bitmap.getConfig()), 0, 0, p);


//        canvas.drawPaint(p);

        return bitmap;
    }
