image edge detecting的意思|示意

I am trying to convert a text document to a binary image by first detecting its edges and then converting it to a binary image based on output of edge detection.

我试图将文本文档转换成一个二进制图像，首先检测边缘，然后将它转换成一个二进制图像基于边缘检测的输出。

An edge detecting method for digital image is proposed using direction information of the gradient to thin off the differential image and defining a measuring function to link the edge points.

本文提出了一种利用梯度的方向信息，对微分图象进行细化，并确定一测量函数进行边缘点连接，以实现图象边缘检测的方法。

In a word, the method of this paper is an efficient edge detection algorithm for detecting edges from noised image.

总之，该算法能有效地从噪声图像中检测出边缘。

So an edge detection method based on phase information is presented, which is more efficiency in detecting the NOSM image edges than the method based on intensity.

针对这种情况，本文提出采用基于相位信息的边缘检测方法，克服了基于图像强度信息进行边缘检测的不足，有效地提取了近场光学图像的边缘信息。

The image processing algorithm of slide abrasion detection is designed in this paper. It includes image preprocessing, edge detecting and linking, contact wire and slide edge location and etc.

本文设计了滑板磨耗图像检测算法，主要包括图像预处理，边缘检测和连接，导线及滑板边缘定位等。

So the paper definitely has some reference value not only for the image inspecting ways of slide wear but also for the design and realization of edge detecting and location algorithm.

本文对滑板磨耗图像检测的方法以及边缘检测及定位算法的设计和实现都具有一定的参考价值。
