中文说明：一种在频域中可逆地将数据嵌入数字图像的方法，其基础是对图像应用整数变换，然后选择中间子带中的一些子带并选择某个位平面并对其进行压缩，然后将压缩的位平面与有效载荷连接起来，并用该数据替换所选的位平面。
English Description：
a way to embed data reversibly into a digital image in the frequency domain based on applying an integer transform to the image then selecting some a middle sub-band and selecting a certain bit-plane and compressed it then concatenate the compressed bit-plane with the payload and replace the selected bit plane with that data.
