图像压缩

Plentiful emulation experiments show that the algorithm ensures the watermark's imperceptibility and robustness, and is also robust to familiar image processing such as JPEG compression , noise contamination, cropping, zoom and circumrotate etc.

通过大量的仿真实验，证明本文算法在保证水印不可见性的同时，对常见的图像处理，如JPEG压缩、噪声、剪切、缩放以及滤波等，均具有较好的鲁棒性。

It is a network terminal which is connected with digital television; it is used for transforming digital signals to analog signals. After decoding the digital constringent video and audio signals, it will engender analog video and audio signals. Consequently, it can provide high quality television program for audiences.

它是一种与电视机连接的网络终端设备，用于将数字电视信号转换成模拟信号，它通过对数字化压缩的图像声音信号进行解码还原，产生模拟视频和声音信号，以提供给观众高质量的电视节目。
