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。

In the process of the image compression, the use of evolution-function makes this evolvable hardware be able to search for the best prediction function.

在压缩过程中以函数进化的方式，使该进化型硬件能够根据图像的特点来探索最优预测函数。

But this algorithm will brings truncated-error into the reconstructed images, it was unfit for the medical image compression that was exigently in reconstruction image quality.

然而由于Mallat算法存在较大的截短误差，不太适用于对还原性要求较高的医学图像的压缩。

Corresponding to some application problems,other practical advanced schemes are presented,such as,combining compression with filter operators,utilizing image sequences and replacing original image with featural pictures.

然后，针对一些应用问题，进一步讨论了改进压缩比的若干方法，包括与滤波算子的结合、图像序列的利用以及用特征图来代替原图。

Therefore, it is necessary to design efficient compression methods according to the features of interferential hyperspectral image.

作为一种三维图像，其海量的数据导致存储与有限带宽信道上的传输非常困难，因此必须针对其数据特点设计高效的压缩编码方案。

Experimental results show that, the method is better than Ker's calibrating method, especially in detecting uncompressed high resolution raw image due to its simple realization without estimating the embedding rate beforehand.

实验结果表明，该方法要优于Ker的校准法，尤其对未压缩的高精度原始图像的检测更为有效，并且不用估计嵌入率，方法简单，易于实现。

The date of decoding shows that: the video after decoding retained the original image quality, but the date loss lessness.

解码后的数据显示：压缩视频被解码后保留了原图像的质量，而且数据丢失量小。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
