Fault isolation is an essential step in multivariate statistical process monitoring, which discovers the cause of the detected fault. The common adopted techniques for fault isolation, such as contribution plots, reconstruction analysis, branch and bound, etc., often suffer from the problems of the smearing effect, insufficient historical fault data, and heavy computational burden. In this paper,...
This letter presents an approach to extracting a target object interactively from a given pair of stereo images. First, a user marks a few parts of the object and background in either of the two views with strokes. The marked pixels are used to generate the prior models of the foreground and background. Second, a graph is constructed with constraints formulated by the priors of foreground/background,...
It is hard for current interactive stereo image segmentation methods to deal with large scale images with fast feedback after each interaction. In this paper, we present an interactive stereo image segmentation method. Different from current methods, our method introduces a multi-scale graph structure for fast graph cut optimization. Besides, we use GPU parallel computing to handle single instruction...
In LTE system, HTTP streaming services sometimes experience video quality deterioration because of the constraint of available wireless resources, which leads to reduce of Quality of Experience (QoE). In this paper, we propose a new scheduling scheme which is QoE-oriented from user's perceptive to improve the performance of HTTP streaming service in a LTE system. First of all, we adopt the jerkiness,...
Optimizing reservoir flood control operation is one of important non-structure measures for reducing flood damage. However, reservoir flood control operation is a typical, complex, and nonlinear optimization problem. It is very difficult to directly solve this problem. Linear programming and dynamic programming are usually used to solve it, which can bring big error or curse of dimensionality. IPOPT...
A new method for evaluating roundness error using polar measurement data, which named as polar mesh searching algorithm (PMSA), has been presented in this paper. The principle of the algorithm was that series of polar-coordinate mesh points were collocated around the periphery of the least square circle according to certain rule, the radius of all the measured points were calculated by regarding each...
