stochastic noise meaning in Chinese
随机噪声
Examples
- Frequency domain multiple input output modal parameters identification with consideration of stochastic noise
计及随机噪声的频域多输入多输出模态参数识别 - Experimental results show that the embedded digital watermarking is invisible and robust enough against common image processing such as jpeg compression , filter , adding the stochastic noises and shearing
实验结果表明：使用该算法嵌入的数字水印具有很好的隐蔽性，并且嵌入水印的图像对有损压缩、滤波、加入随机噪声和剪切等攻击操作具有较强的鲁棒性。 - Compared with the hardware compensating , the software compensating can not only simplify the design of circuits , reduce the cost , but also enhance the ability of getting rid of stochastic noise , stability , and accuracy , at the same time , the capability of the processor is sufficiently presented
软件补偿与硬件补偿相比,不但大大简化了硬件电路设计,降低了产品成本,而且抗干扰能力,稳定性,精度都有很大提高,同时也充分发挥了arm处理器的性能。 - In order to adapt the scheme to both the color image and the gray image , while embedding the watermarking into the image , the scaling factors are determined by the local luminance feature and texture features of the image . it can improve the embedding strength and the watermarking robustness . from the experimental results , the stego - images are extremely robust to common image processing such as median filter , jpeg compression and denoising after adding the stochastic noises
2 、提出了一种新的基于小波变换和纹理特征的数字水印算法，该算法依据从图像小波域提取出的纹理特征来选取水印的嵌入位置，较好地利用了图像的纹理区域，既能掩蔽较多的噪声，又能较好地抵抗jpeg压缩等一般性攻击，调节了数字水印技术中存在的不可见性与鲁棒性之间的矛盾。 - Two conclusions about suspending control system are given in this paper : 1 . the single suspending system controlled by parameter self - turning control algorithm has better performance when the mass of single point suspending system , the resistance of electromagnet and the suspending gap are variable ; 2 . the single suspending system controlled by global asymptotic stability control algorithm is global asymptotic stability and can restrain the stochastic noise
通过对采用上述控制算法的悬浮系统的理论分析和仿真研究,主要得到了以下几方面结论: 1 .当系统悬浮质量、电磁铁电阻和额定间隙参数变化时,设计的参数自校正控制算法可使系统的动态性能指标保持在设定的指标; 2 .设计的全局稳定控制算法,能够保证二级结构单点悬浮系统的全局渐近稳定,且对随机噪声干扰有一定的抑制作用。
