Abstract
The result of the image processed by traditional edge detection operator is an edge sharpening gradient image.In order to get the binary edge image,it requires determining the threshold artificially.The loss of edge information is caused.So it uses the Sobel operator with increase convolution mask to get the gradient image.The threshold value through the steps K-means algorithm based on gradient histogram is got,the binary edge image is obtained by segmenting gradient image which uses the acquired threshold value,the edge is thinned and connected.The Otsu algorithm is used to check the correctness ofthreshold value and different edge detection approaches are compared with improved method.It obtains reasonable threshold value and has a better performance than improved Sobel operator and the result is close to Canny operator with optimal threshold.It can be applied in the field of machine vision.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
