高斯模糊的Java实现

public static byte[] blur(byte[] data) throws IOException {
        ByteArrayInputStream bais = new ByteArrayInputStream(data);
        BufferedImage img = ImageIO.read(bais);
        GaussianFilter gaussianFilter = new GaussianFilter();
        gaussianFilter.filter(img, img);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ImageIO.write(img, "jpg", baos);
        return baos.toByteArray();
    }
