TL;DR: The result shows that, when the parameters of the Harris corner detection algorithm is improved, it can highlight the corner and background contrast, reduce the complexity of the threshold value to a certain extent, and the result is better than the classical Harris algorithm.
Abstract: Corner is an important image features,we provide theoretical analysis and experimental study of the classic Harris algorithm. We propose a theoretical analysis of parameter values in the improvement,and validate the analysis results based on the related program testing. The result shows that,when the parameters of the Harris corner detection algorithm is improved,it can highlight the corner and background contrast,reduce the complexity of the threshold value to a certain extent,and the result is better than the classical Harris algorithm.

TL;DR: In this paper, an image filtering method to extract connected domain in binary image is presented. But the noise suppression effect is not as ideal as expected as expected, when using common noise filtering methods to suppress the target image, it presents an image filter method that extracts the images connected domain and communicates according to the outline of the selected field noise point and filter noise point, which preserves image detail and effective noise suppression characteristics of the target images.
Abstract: In order to address the noise suppression effect is not as ideal as expected,when using common noise filtering method to suppress the target image,it presents an image filtering method to extract connected domain in binary image The collected binary image extracts the images connected domain and communicates according to the outline of the selected field noise point and filter noise point,ultimately preserves image detail and effective noise suppression characteristics of the target image Results show that this method is superior to conventional filtering methods in a particular application

TL;DR: In order to help the college students employment guidance of science, Analytic Hierarchy Process Career is used, which shows that the right weight of the large-scale state-owned enterprises is higher than the big institutions and private enterprises of good reputation.
Abstract: In order to help the college students employment guidance of science,we use Analytic Hierarchy Process Career the college students issues mathematical modeling,and decision-making related to the elements will decompose into goals,guidelines,programs and other levels,the establishment of a hierarchy of models. By constructing judgment matrix,consistency checking calculations and sorting,and on this basis,the problem of the college students choosing is taken a qualitative and quantitative analysis. The results show that the right weight of the large-scale state-owned enterprises is higher than the big institutions and private enterprises of good reputation. When the college students are chosen employment,they value most is the unit's reputation,followed by opportunities for advancement and professional counterparts.

TL;DR: Aiming at solving problems of information sharing and integration between CAD,CAPP and CAM systems, a framework based on PDM database for CAD / CAPP / CAM integrated system is established, so that the product design information, process information, manufacturing information and other data relevant to the parts machining process are built and stored in thePDM database.
Abstract: Aiming at solving problems of information sharing and integration between CAD,CAPP and CAM systems,a framework based on PDM database for CAD / CAPP / CAM integrated system is established,so that the product design information,process information, manufacturing information and other data relevant to the parts machining process are built and stored in the PDM database. The data information of product is safely and effectively managed. Meanwhile,according to the analysis of the processing characteristics of shaft parts,the geometric feature models,process information models and processing simulation models are set up. According to the design of VB programming language,the automatic generation of process chart is implemented with example analyses of shaft parts. As for the purpose of information exchange and sharing in the design,management and manufacturing process,the management and production efficiency is greatly improved.
