Android : converting RGB888 to Y800

Question

I am getting image captured from vuforia as RGB888 bytes[] . I want to pass this to zbar which is expecting the format to be Y800 . How can i do that.

i tried

Image barcode = new Image(width, height, "RGB3");

    barcode.setData(imgRGB888);
    int result = scanner.scanImage(barcode.convert("Y800"));

but its not giving right result
