Manual methods are used to perform the classification of coarse carbides in metallic material, so a quantitative standard is needed necessarily to achieve the automatic classification. In order to obtain the standard and further perform processing and analysis of carbide metallograph, area histogram which was used in image retrieval is first introduced to metallographic analysis field. Average area...
This paper studies the problem of the real-time communication in the on-line monitoring system, which achieves the on-line monitoring of B / S mode through the ActiveX controls and network programming technology based on the TCP / IP protocol. This paper proposes an improved congestion control algorithm grounded on the one-way delay (CCAOD), using the value and the change trendency of the one-way...
Manual methods are used to perform the classification of coarse carbides in high speed tool steel these days, so a quantitative standard is demanded necessarily to achieve the automatic classification. In order to obtain the standard and further perform processing and analysis of carbide metallograph, area histogram used in image retrieval is first introduced to metallographic analysis field.

On the basis of analyzing the blur images with noise, this paper presents a new segmentation method which is based on the morphology method, fuzzy K-means algorithm and some parts operator of the Canny algorithm. Because of the Canny's good performance on good detection, good localization and only one response to a single edge, we introduce the course of Canny operator that calculating the value and...
The algorithm of fractal dimension and co-occurrence matrices is proposed and is applied to material Vickers hardness image segmentation. Based on the characteristics of the indentation images, this article uses texture features to extract the indentation silhouette from the point view of texture segmentation. We adopt fractal dimension and co-occurrence matrix algorithm to describe the texture characteristics...
The paper studies the intelligent detection system based on TCP/IP protocol and realizes real-time detection based on B/S mode. This article focuses on the real-time problem of the communication system, an also propose an improved algorithm of congestion avoidance based on receiver-driven(CARD). Being different from the RTT algorithm and some traditional algorith, CARD uses one-way delay detecting...
In this paper, structure and working principles of eddy current retarder (ECR) are discussed, as well as performance requirements of real-time virtual testing and simulation. On the basis of hardware testing platform, virtual models of vehicle and retarder are embedded into application program. In the testing system, Vega API function library is used for second development to control the 3D models,...
High SNR (signal to noise ratio) image is deeply needed in the precise analysis of IC wafer micro-image; current denoising algorithms cant reach the analytic precision in some level. In tins paper, one image denoising algorithms is putted forward based on adaptive lifting scheme, the construction of Haar wavelet and CDF (2,2) is given, the signal is decomposed by wavelet base Haar or wavelet base...
In this paper, based on the electrothermal upsetting processing method, the process of valve upsetting is divided into two steps: initial upsetting and formal upsetting. Four parameters, including 1.hearting current; 2.press; 3.velocity; 4.material, which influence the manufacture process in evidence, is mainly discussed. Analyzing defect and deficiency of tradition processing, the article puts forward...
