| 1. | It is also wise to stop adding noise functions when their amplitude becomes too small to reproduce 当振幅变的很小的时候,也应该明智的停止再叠加噪声函数。 |
| 2. | The street itself was ugly , too . it had no pavement and no street light . the railway at one end of gates avenue added noise and dirt 街道本身也很丑陋。既没有人行道,也没有街灯。其中一端的铁路增加了噪音和灰尘。 |
| 3. | Auv ' s position control and velocity control are researched and s imulation experiment i s carried out at two situations : in blue and whisht water and in water with current and adding noise 本文设计了auv位置控制器和速度控制器。并对深海静水和有海流噪声两种情况进行了仿真试验。 |
| 4. | Congratulations ! , you ' re nearly there . now you just need to take your 3 shadow elements and take them through the process outlined above to blur , add noise and alter their opacity correctly 祝贺你!你马上要成功了。现在你只需要把你的3个阴影元素放到合成中并添加噪声、恰当的设置他们的透明度。 |
| 5. | Attack the watermarked image through adding noise , filter , and jpeg compress . in the extracted watermark from the attacked image , the important part , which is embedded into frequency domain , has good robustness 对含水印图像进行噪声、滤波、 jpeg压缩等攻击,确保了dct域中的重要部分有良好的鲁棒性。 |
| 6. | The experiment results show that the watermark embedded is rather robust to various attacks such as adding noise , rotation , translation , scaling , insecting , down - sampling and some of their combinations 实验表明该算法鲁棒性较好,对噪声、旋转、平移、缩放、剪切、降采样及其联合攻击的抵抗性较强,并且算法复杂度较低。 |
| 7. | In the final , we evaluated and analyzed the quality of a series of compressed images with the fuzzy image and psnr ( peak signal - to - noise ratio ) measurement . we have also made some other experiments such as add noise to the images and so on 然后用峰值信噪比和本文提出的模糊图像度量分别对一系列压缩后的图像质量进行评价,并且分析了它们的评价结果,最后还进行了对图像添加各种噪声等实验。 |
| 8. | Based on discussion of sar high resolution and theoretical imaging model and existent simulation of sar digital processing , a more convenient and useful model is built that realizes dialogue between man and computer and has a interface of adding noise signal 该课题的研究使sar的接收处理过程在计算机上得以实现,并且方便应用于今后的机载sar研究和电子对抗研究工作,具有一定的参考和应用价值。 |
| 9. | The adaptive sr , studied in this thesis , means that the system automatically selecting parameter with a recursive algorithm , not adaptively adding noise . a parallel connection sr system is introduced and its application in digital frequency shift modulation signal transmission is discussed 我们初步提出了参数自适应随机共振的思想以及收敛算法,同时,我们还研究了数字信号载波调制传输中的并联随机共振系统。 |
| 10. | It is demonstrate that sr realized by turning system parameters can be explained as sr via adding noise after a transformation . it is found that sr via turning noise could be made equivalent to turning system parameters and adjusting signal amplitude accordingly . but the psr method can appear under the more worse environment than sr via adding noise does 本文对于参数调节随机共振与传统的噪声调节随机共振联系与区别进行了研究,经过尺度变换后,二者是可以相互解释的,参数调节随机共振就是寻找传统的噪声调谐共振峰值所对应系统的一种理论和方法,它具有适应范围广和调节方便的优点。 |
