查询词典 noise

In order to effectively abstract the texture and denoise but not damage the edge and other important details of image, Meyer (2001) proposed using elements of BV space and G space to characterize cartoon and details of image respectively. The authors present PDE of minimizing energy on the basis of Meyer's work, After the model is discretizated. projection algorithm and the method for ROF model are applied. Thus an image is decomposed into two parts, bounded variation component u and texture with noise υ.

为有效地提取纹理和去噪而不损坏图像的边缘及其他重要细节，Meyer(2001)提出了分别用BV空间和G空间刻画图像的主体和细节部分，笔者在Meyer的图像分解模型基础上，建立能量最小化PDE方程，将模型离散化后，利用投影算法和ROF模型的求解方法，将图像分解为有界变差部分u和包含纹理和噪声的部分υ。

After the model is discretizated,projection algorithm and the method for ROF model are applied.Thus an image is decomposed into two parts,bounded variation component u and texture with noise v.The numer...

数值实验表明，此方法仅用共40次迭代就能达到很好的分解效果，且去噪的信噪比比ROF模型提高了29.95%，而且除能有效地提取纹理和去噪外本方法对图像的边缘及其他重要细节损坏较小。

Influenced by both lateral velocity variation and some noise waves bow tie, side wave, diffracti...

由于受回转波、侧面波、绕射波等互相干涉和速度横向变化的影响，叠加剖面成像质量较差，造成构造形态失真。

A trap door appears abruptly behind the big chair and Mr.Jin withdraws with the chair into the door then it closes. Tung San smiles and boxs forward in air. The box blast hits on the trap door and makes a loud noise. Soon, the floor in fornt of the door sinks and a huge pole knocks down on the place floor sinks.

太师椅后突然出现一个暗门，金老爷连人带椅退了进去，暗门随即关上，童三微笑一下，一掌凌空劈出，掌风撞在暗门上，发出咚的一声大响，立刻暗门前的地板就陷了下去，一根大柱随即打在地板陷落处

Firstly, we analysis the principle of fluorescence emitting. Secondly we design a signal detection system based on digital BOXCAR, considering with the feature of the fluorescence signal and the noise background.

首先分析了荧光信号产生的机理，在此基础上考虑到荧光信号十分微弱的特点和在强噪声背景环境下检测，设计了基于数字BOXCAR的信号检测系统。

The feasibility of an application of particle damping to the noise and vibration control of a drum brake was analyzed. The characteristics of the damping were tested.

Experiments show that the algorithm can extract the affine-invariant line skeleton, resist the noise and automatically determine the branch point and key point in the skeleton.

该算法能够从散乱点集上得到一维"线"性的骨架，具有仿射不变性，能够抵抗一定的噪声，自动确定骨架上的关节点和分支点。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
