其次，本文将HHT方法应用于眼底图像边缘检测，提出了基于二维经验模式分解（Bidimensional Empirical Mode Decomposition，简称为BEMD）的图像边缘检测算法。

To avoid blurring of the real edge, this algorithm also combined the gradient information of several block boundaries to distinguish the blockiness and the real edge.

为了避免真实边缘被模糊，该块效应消除算法还联合多个块边界的梯度信息来区分块效应与真实边缘。

Canny edge detection that the image edge detection method is the best way.

证明了Canny边缘检测方法是图像边缘检测的最佳方法。

Single leaf alternate, oval to lanceolate , there is a clear and thick jagged edges or deep cleft, base wedge-shaped, with petiole, the first capitulum solitary or a few stems and branches set born in the top of the outer phyllaries green multi-layer, strip, edge membranaceous; tongue Flower-shaped yellow, red, purple or white or light green.

This method supplies the steady edge data to the fused edge.(5) Feature vector, which includes sign of edge, central angle and the distance from chord to the circle center, is served as the role of feature association.

s在亚像素条件下，将边缘符号、圆心角和弦心距作为特征关联要素，建立了不同光学影像之间的边缘特征关联和融合定位模型。

The flat sheet has a clasper at its one edge to hold end edge of display card and there is a fan located in the first plane.

平板其中一边缘具有一卡勾，夹持于显示卡的边缘。以及一风扇，位于第一平面。

Therefore, based on analysis the relation of edge density distribution and the ratio, an adaptive multiscale edge detection method is proposed.

基于这个比值与边缘密度分布关系，提出了基于区域能量的自适应多尺度边缘检测方法。

First, we smooth the tongue picture. We detect the tongue edge by wavelets and a method of which is based on color information differentiability.

首先，我们对舌象进行平滑去噪，再利用小波和基于彩色信息区分度的彩色边缘检测方法提取舌象边缘，获得舌面区域。

ResultsMacroscopic examination showed no excrescence,thrombus formation,arm fractures and corrosion.The devices were covered with collagen fibrosis and discrete endocardial cells,apparent inflammatory infiltration in the devices and around the devices 1 month after implantation.The implants were nearly endothelialized,while the inflammatory reaction relieved gradually,with myocardial cells ingrowth at the edges of the device 3 months after implantation.The devices were completely covered with endocardium and fibrous tissue.Moreover,endothelial cells could be found on the smooth microscrew adaptor.The inflammatory reaction diminished with a few chronic inflammatory cells existing.Neovascularization and lymphatic vessels ingrowth could be observed 6 months after implantation.

结果所有封堵装置表面均没有发现赘生物、血栓形成、支架发生断裂及被腐蚀；术后1个月，封堵装置表面被胶原纤维和散在内皮细胞所覆盖，大量炎症细胞浸润，封堵装置边缘有小灶性炎症细胞浸润；术后3个月，封堵装置表面几乎被内皮细胞所覆盖，炎症细胞较1个月时明显减少，封堵装置内见纤维化，封堵装置边缘心肌细胞浸入；术后6个月，封堵装置表面完全被心内膜和纤维组织所覆盖，伞尖表面光滑并有内皮细胞上爬，炎症反应明显消散，但仍有少量慢性炎症细胞存在，装置内有新生的血管、淋巴管长入。

The results indicated that visitors' activities caused a serious influence on the soil in the park, especially in the two most used scenic spots-Yellowstone Village and Gold Whip Stream. The impact of tourism on soil mainly occurred within 3 m along the trails. The impact shapes are classified into six type as single-sided node type, double-sided node type, cross node type, single-sided linkage type, double-sided linkage type and short-cut linkage type. Of six types of impact shapes, the single-sided node type and double-sided type were dominant. The average water contents of soil for six scenic spots at sample areas of 1 m, 2 m and 3 m from trial is 36.6%, 24.5% and 2.2% lower than that of the control area, respectively. The average soil hardness for six scenic spots at 1m, 2 m, and 3m from the trails tramped increased 167.9%, and 122.2%, and 15.8%, respectively, compared with the control area. Soil bulk density increased 26.5% at 1 m and 20.9% at 2 m from the trails.

结果表明：游客活动对张家界世界地质公园土壤产生了较大的影响，特别是在游客相对集中的黄石寨景区和金鞭溪景区，影响十分明显；游客对土壤影响的范围主要发生在距游道两侧3米以内的范围；公园内土壤影响形态可分为单侧节型、双侧节型、单侧链型、双侧链型、十字节型和捷径链型6种类型，其中又以单侧节型和双侧节型为主；在六个景区中，距游道边缘1米、2米及3米范围内土壤的平均含水率较对照区分别低了36.6%、24.5%和2.2%；与对照区相比，距游道边缘1米、2米及3米的土壤硬度分别增加了167.9%、122.2%和15.8%，而距游道边缘1米和2米范围内的土壤容重则分别比对照区增加了26.5%和20.9%。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
