图象失真

We also pursue the relations between 〓-distance and distortion-rate function, and obtain some interesting properties that are useful in the proof of coding theorem.

对于有失真情形，文章在简单总结率失真函数理论发展及其在图象压缩中的应用后，引进了随机场失真率函数的定义并证明了其重要性质。

Image enhancement refers to the dura image enhancement, the useful information, it can be a distortion of the process, its purpose is to enhance the visual effect.

图像增强是指增强图象中的有用信息，它可以是一个失真的过程，其目的是要增强视觉效果。

The flatness of screen of the picture tube generates extension distortion of the picture, or pincushion distortion.

显象管荧光屏的平面性，使图象生延伸性失真，即枕形失真。

While corner sharpness is good, it produces significant barrel distortion at the wide-angle end,and some pincushion distortion at the telephoto end.

虽然边缘图象的清晰度不错，但广角端产生了比较大的桶形失真，在长焦端也少许枕形失真。

On the basis of the statistical characterestics of satellite meteorological infrared cloud charts this paper presents a coding algorithm of "Sub sampling+Modified JPEG+Image enlarging",realizing a compression ratio of 50∶1～100∶1, with the PSNR of 35～40dB and visually unperceptible distortion.

依据GMS卫星红外气象云图的统计特性，提出了一种&亚抽样＋修改的JPEG＋图象放大&的静止图象编码方法，使有失真压缩比在50∶1至100∶1时，恢复图象峰值信噪比在35dB～40dB之间，主观质量无视觉可觉察到的失真。

Thermal bad】【display, CPU power and heat in the work of very large, so good ventilation is very important, if the display color will lead to overheating, to reduce monitor image distortion and even life.

显示器、电源和CPU在工作中发热量非常大，因此保持良好的通风状况非常重要，如果显示器过热将会导致色彩、图象失真甚至缩短显示器寿命。

This may result in a distorted or miscolored picture.

结果会造成图象扭曲和颜色失真。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
