These results have some reference value for selection of these edge-detecting operators.

然而，边缘检测又是图像处理中一个困难的问题，因为实际图像中的边缘往往是各种类型的边缘以及它们模糊化后结果的组合，由于实际图像中存在着不同程度的噪声，各种类型的图像边缘检测算法不断涌现，但对于不同算法边缘检测结果的精度却没有一个统一的衡量标准。

When detecting the edge, an auto-choose threshold algorithm is given to reduce the salt-and-pepper or pulse wrong edges. After analyzing the special noise factor in pin's image, this paper improves the edge detection elements. That's putting forward a way which is named"the method of de-noise based on linear weighted operator template"to reduce the zonal or cluster noise. And test show that the algorithms detect image's edge rightly.

针对钻针图像的特点，在边缘检测中提出了自动选择阈值的算法；之后针对钻针图像中的特殊噪声形式，对边缘检测算法进行了原理上的改进，通过对图像的灰度分布的数学模型的建立，提出了使用加权直线模板去噪法进行块状噪声的去除；通过上述算法的应用，良好地改善了图像处理的质量。

Making use of the powerful capabilities of the PCI chip, high-speed data of the DSP platform are transferred both ways at DMA mode, and low speed data such as initialization and configuration information are transf...

On the basis of that, an indepth analysis and discussion on the image processing approaches based on swarm intelligence from the human visual system and bionics point of view was given. It was compared with the traditional image processing approaches.

在此基础上，从人眼的视觉结构以及仿生学的角度出发，对基于群体智能的图像处理方法的基本思想进行了深入的分析和探讨，并与传统的图像处理方法进行了比较。

Compared with the traditional methods used in the image processing, this approach offers advantages of taking into account the correlation of the whole image, keeping fine details of image and avoiding the sawtooth effect and smoothing effect associated with traditional image interpolation techniques.

与图像处理中的传统插值算法比较，该算法通过提取图像的分形特征保持图像的全局相关性，更好地保持图像的细节信息，避免了传统插值算法引起的锯齿效应和平滑效应。
