The measurement system is consisting of a 3D ECT sensor with 12 electrodes, a WK65120B impedance analyzer, a specially designed multi-channel switched system and a PC. Using the QT software to control multi-channel switch system and impedance analyzer, we can achieve the automatic capacitance measurement of 12 plates of 3D capacitance sensor without affecting the measurement accuracy, and save the measurement data on the computer. Compared with direct impedance analyzer, the measurement speed and stability are improved. Experiments show that the system can automatically measure all the 66 capacitance values generated by the 3D ECT sensor with low drift, high resolution and high accuracy.","PeriodicalId":448698,"journal":{"name":"2013 IEEE International Conference on Imaging Systems and Techniques (IST)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122753386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike the semantic parts based on high-level concepts, the visual segments prefer focusing on the low-level visual features which are easier to find and match from one image to other image by simple similarity measurement. Towards this goal, an iterative process is performed in the image set, including the appearance models learning and the energy function minimizing. The initial appearance models are learned from the image set according to the saliency measurement and the objectness measurement, including the segment models and the background model. Specifically, a novel inter-image constraint is exploited in the energy function by using the layout-based similarity measurement. By experiments on a variety of image datasets, the proposed approach efficiently segments and parses the object instances with varying appearance and shape, under challenging environmental conditions.","PeriodicalId":448698,"journal":{"name":"2013 IEEE International Conference on Imaging Systems and Techniques (IST)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132759267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integrated system included INS/GPS and INS/aerial-image two subsystems, the outputs from two subsystems were fused in the main filter. Finally, optimal parameters of the system state estimation were obtained. Experimental results show that the proposed method well solves the error divergence problem over time with INS, and prevents the truncation error generated by EKF algorithm.

For the circular area, three different measuring strategies are considered, and then compared with a traditional ECT sensor (EE). For the annular area, three different measuring strategies, the internal electrode with/without screen, the EE sensor are considered and compared.

Images are often high-dimensional patterns, and dimensionality reduction can enhance processing and also increase classification accuracy. Specifically, our technique maps images into networks and constructs two network adjacency matrices to convey information about intra-class components and inter-class penalty connections. Both matrices are inserted into an optimization framework in order to achieve a projection vector that is used to project high-dimension data samples into a low-dimensional space. One advantage of the technique is that no parameter is required, that is, there is no need to select a model for the input data. Applications on handwritten digits recognition are performed, and the proposed technique is compared to some classical network formation methods. Numerical results show the approach is promising.","PeriodicalId":448698,"journal":{"name":"2013 IEEE International Conference on Imaging Systems and Techniques (IST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132326958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This means especially that their solution is unstable under data perturbations. Numerical methods that can cope with this problem are the so-called regularization methods. The choice of a regularization parameter has an important influence on reconstruction accuracy. In this paper, a 3D acoustic temperature field reconstruction algorithm is proposed. It uses a new criterion for choosing the regularization parameter, which makes a good compromise between de-noise and detail reconstruction of the temperature field. Reconstructions of a single-peak temperature field by using simulated travel-times corrupted with different level noises demonstrate that the new algorithm has high reconstruction accuracy and good anti-noise ability.","PeriodicalId":448698,"journal":{"name":"2013 IEEE International Conference on Imaging Systems and Techniques (IST)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121540610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, suitable pairs of azimuth data between sparse angle sectors are chosen for coherent processing. Then we use de-noising cross-correlation algorithm and statistical method to obtain phase incoherent parameters (ICP) between sparse angle data. After compensating the phase ICP, a coherence function is defined to achieve amplitude ICP. Finally, data interpolation and extrapolation via two-dimensional gapped-data state space approach (2-D GSSA) are applied to sparse angle data and high-resolution imaging of the targets is achieved. The method is especially useful for sparse angle sectors with small gaps.
