Secondly, in this paper, it described and analyzed the segmentation method based on the edge in the domain of image segmentation in detail. It did experiments on several edge detection operators using MATLAB, it summarized the advantage and the shortcoming of traditional edge detection operators, and the operating environment. On the basis of the experimental analysis, it implemented an edge location more precise, more efficient operating speed edge extraction method——Template Vector. In this method, it optimized differential approximate calculation of first differential operators the paper mentioned. After experimented on this edge extraction method, contracted with the traditional methods, the edge outline is extracted more accurately and more exquisitely, furthermore, it retained the object outline furthest, and achieved more satisfied edge extraction result.

In doing back-up data, we followed the work to be done is to switch to a system running DOS, and DOS command line in the implementation of "fdisk / mbr" command string to try to repair the hard disk of soft failure occurred ; if such a repair method to try is invalid, then we can go online to download and install the hard drive Bad Track professional testing tool to double-check the local hard disk in the phenomenon of the existence of Bad Track, Bad Track If you can not find the hard disk, it can not detect hard drive through the phenomenon is likely to be caused by the logic of failure, when the only thing we can use the way is hard to find the logic of the corresponding brand Bad Track Repair Repair Tool to re-click the hard disk, I believe that case the hard disk will be able to detect the phenomenon can not be resolved the.

在做好数据的备份工作后，我们接下来要做的工作就是将系统切换到 DOS 运行状态，并在 DOS 命令行中执行" fdisk /mbr "字符串命令，来尝试修复硬盘中发生的软故障；要是这种修复方法尝试无效的话，我们可以到网上下载安装一些专业的硬盘坏道检测工具，来仔细检查本地硬盘中是否存在坏道现象，如果找不到硬盘坏道的话，那硬盘检测无法通过的现象很可能是逻辑故障引起的，此时我们唯一可以使用的办法就是找到对应品牌硬盘的逻辑坏道修复工具来重新修复一下硬盘，相信这么一来硬盘检测无法通过现象就能被解决了。

When an interpolation filter is designed, the edge exists in the image is acquired through the multi-directional edge detection and the analysis of the fake edge and the weak edge; the interpolation is correspondingly processed according to the motion state and the edge direction of the pixel point; the field resulted from the interpolation and the interpolated field are interlaced to form the non-interlaced video image.
