查询词典 on edge

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

On the edge of the coin is the cross-crosslet mintmark of Llantrisant and the Latin inscription DECUS ET TUTAMEN, meaning 'an ornament and a safeguard' which first appeared on the edge of coins of Charles II to deter the unscrupulous practice of clipping and shaving precious metal from the coins.

硬币周围环绕着100个珠型图案，象征100便士即1英镑，侧面为皇家造币厂早期的标志---小十字型花纹及拉丁题字DECUS ET TUTAMEN，寓意为&装饰和捍卫&。为了防止人们从币上涂刮稀有金属，这种侧面图案在查尔斯2世时代首次出现。

Most traditional algorithms of image edge detection use gradient maximum or zero-crossing based on gray discontinuousness on edge. They are affected easily by noise.

传统的边缘检测算子大都基于边缘的灰度不连续性，利用梯度局部最大值或二阶导数过零点来检测边缘，容易受噪声干扰。

Blood speckle noise in the IVUS image would affect the validity of edge detection badly. A temporal/spatial filtering method was used to preprocess the IVUS image to restrain the noise. Then a method to automatically detect the intima and ectoblastic edge of IVUS image was presented. This method is based on the active contour model and the contrast properties of IVUS image, which makes use of the Hopfield NN and simulated annealing algorithm.

为解决血管内超声图像中严重的血液斑点噪声影响边缘提取方法的有效性问题，采用一种时/空滤波方法对IVUS图像进行降噪预处理，基于活动轮廓模型和IVUS图像的边缘对比度特征量，利用Hopfield神经网络并结合模拟退火算法自动提取IVUS图像的冠脉血管壁内、外膜边缘。

Common buckwheat, also known as buckwheat, and its flowers have a nectary can scent to lure insects, cross-pollination; Fagopyrum tataricum Tatar, also known as buckwheat, a small flower, no fragrance, self-pollination, artificial hybridization extremely difficult to successfully ; As winged buckwheat buckwheat and rice is the achene edge node as a result of their wings was like thin or plump achenes splitting between the two edge, easy-exposed fruit in the "m" name.

甜荞又称普通荞麦，其花中有蜜腺，能散发香味，引诱昆虫，异花授粉；苦荞又称鞑靼荞麦，花器小，无香味，自花授粉，人工杂交极难成功；至于翅荞和米荞则是由于其所结瘦果棱薄呈翼状或是瘦果两棱之间饱满欲裂，易露出果内的&米&而得名。

Because the proposed model has the property of multi-scale, the excellent anti-noise in the interior of the region, and the noise weakening faintish edge, the corresponding algorithm has good performance in image edge detection.

该模型具有多尺度、区域内部抗噪能力与尺度有关、噪声弱化弱边缘以及边缘具有隶属度、图像的边缘检测结果与尺度有关等特点，反映了边缘与纹理依尺度的关系。

It was indicated by SEM spectra of ZnO thin films that the surface of the sample was leveled off, and the crystals were felsitic. It was found from the experiment that, with the increasing of substrate temperature, there were more oxygen vacancies in the films, which lead the conductance of the sample become larger , and the absorb edge of ZnO thin films shifted toward higher wavelength; with increasing of Ar:O2 ratio, there were lesser oxygen vacancies in the films, which lead the absorb edge of ZnO thin films shifted toward lower wavelength.

实验还发现，随着衬底温度的升高，薄膜中产生的氧空位将会增多，使得ZnO薄膜的电导逐渐增大，而且其紫外透射吸收截止边带向高波长方向漂移；随着氩氧比例的增加，薄膜中的氧缺陷相对减少，薄膜的透射吸收截止边向低波长方向漂移。

In this paper, we define quadratic spline as wavelet, do the two dimentional dyadic wavelet transform on near-infrared galactophore image, and get local modulus maxima from wavelet transforms results----rnodulus and angles, so we can find the blood vessel edge image in each scales, at last, we compute a good edge image which synthesize the characters in each scale.

本文中用二次样条小波作为小波基函数，对乳腺近红外图像进行二维二进小波变换，计算小波变换结果的局部模极大值点，得到各个尺度下的乳腺近红外图像血管的边缘，最后得到综合了各个尺度特征的较好的血管图像的边缘。
