Thus, the precise motion estimation method of the moving target becomes a hot researching domain. In this paper, a new motion estimation method is proposed for liver vessel tracking using long-term ultrasound free respiration sequences. Firstly, a multi-scale blob-like enhancement filter was implemented to extract the coarse contour of the vessel target region. Then, the level set algorithm based on Chan-Vese (CV) model was used to obtain a fine boundary of the tracking target using the coarse one. The center of the tracking target is considered as the geometrical center of the fine boundary. The proposed method is tested using the clinical US sequences and compared with the traditional cross correlation method. The results show that the proposed method is more accurate and stable than the cross correlation method.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134316736","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}

However, it is widely acknowledged that the performance of Kalman filter depends on the accuracy of priori information such as model structure, statistics information of process and observation noise. Obtaining the covariance matrix of process noise is difficult in some application scenarios. Considering such background, this paper presents a process noise estimation algorithm based on the noise observation sequence. By constructing a transform matrix and removing the state variables from the observation, the noise observation sequence can be established, through which the covariance matrix of process noise can be estimated. Comparing to conventional adaptive filter, this algorithm needs less calculation. Moreover, the noise estimation process is separated from Kalman filter thus ensures Kalman Filters independence and optimality. The simulation results show that the new algorithm can effectively estimate the process noise covariance, and remain uninfluenced by the initial condition.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134483887","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}

Aiming to obtain accurate diagnosis results, we propose a robust approach based on weighted entropy fusion and modified DS theory. The novel algorithm is realized by three steps. Firstly, we present a weighted entropy fusion method to combine four different features of fault signals. Then, we utilize DS theory to synthesize these fault signals from different measurement periods and different combination rules. And finally, a comprehensive decision-making method is applied to export precise fault identification. Simulation results and analyses demonstrate that the neoteric approach can not only get correct and effective fault characteristics under noise environment and limit-precision sensors, but also obtain accurate fault identification. Thus, this paper achieves the goal of safe operation of rotary machinery, which has great application value.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134501849","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}

Through the development of photonic technology, it is perceived that photonic technology will become the new analog signal processing platform with the advantages of the high bandwidth and low loss, so that the function of perception and frequency conversion could be separated from the DSP, thus avoiding digital processing of mass and high energy consumption. In this paper, the received microwave signal is loaded onto the optical frequency comb (OFC) wave, and then the RF signal is input to the Fabry-Perot filter, which has a comb transmission spectrum and filters for a particular frequency periodically. Moreover, the filter has a different free spectral range (FSR) from the OFC. It is for this reason that the frequency of the N-th carrier of OFC differs from that at the N-th transmission peak of the Fabry-Perot filter, and the OFC after comb filtering is spatially divided into different channels by a wavelength division multiplexer. The power of each channel can be obtained by photoelectric detectors and used to estimate the frequency of the RF microwave signals. As the simulation demonstrated, the solution can measure RF microwave signals in a real-time, high-speed, parallel and broadband way.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"531 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876304","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}

Because regularization-based method can solve the pathological problem in super-resolution, so it is widely used. However, in many traditional regularization terms, only the intra-image correlation will be taken into consideration so that the redundancy between adjacent frames is not be utilized. In order to make full use of both inter-image correlation and intra-image correlation, we combine compensation-based TV (CTV) regularization term with multi-non-local low-rank (MNLR) regularization term in our algorithm. Moreover, we utilize a weight matrix to reduce the negative impacts which is caused by registration residuals in CTV, and the weight matrix is based on spatial information filtering and clustering. The experiments show that we can get better results than the compared methods by the proposed algorithm in visual quality and objective effective evaluation.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130388046","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 dechirp method was applied to SAR imaging to reduce the high sample rate and the system storage capacity. The ultra-wideband SAR echo model was built, and the dechirp process was reviewed. Back projection (BP) was adopted to form the two-dimensional complex image. Finally, we have conducted a field experiment on a ground covered by sparse grasses to test the obstacle sensing performance of our ultra wideband SAR, and obstacles have shown special scattering properties in scattering image.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125618319","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}

However, the instability of the basic decisive parameters is ignored in most of the investigations, which might finally lead to a high misjudgement ratio. Therefore, great effort was made to dissect the relationship between misjudgement ratio and the volatility of parameters in this paper. Herein, quantitative analytical for single-parameter network selections and multi-parameter network selections based on linear algorithms was achieved and testified, and qualitative analytical for non-linear multiparameters algorithms was exemplified as well. The simulation results show that the proposed analytical method could depict the trends of misjudgement ratio.

To effectively model the semantic similarity of the SPD matrices and the geometrical structure, a Laplacian smooth operator is incorporated into the objective function of dictionary learning.

However, due to the fact that the number of the parameter is large and the fine-tuning is challenging, the time complexity is high. In order to improve the efficiency, we proposed a tracker based on fast deep learning through constructing a new network with less redundancy. Based on the theory of deep learning, we proposed a deep neural network to describe essential features of images. Furthermore, fast deep learning can be achieved by restricting the size of network. With the help of GPU, the time complexity of the network training is released to a large extent. Under the framework of particle filter, the proposed method combined the deep learning extractor with an SVM scoring professor to distinguish the target from the background. The condensed network structure reduced the complexity of the model. Compared with some other deep learning based tracker, the proposed method can achieve higher efficiency. The frame rate keeps at 22 frames per second on average. Experiments on an open tracking benchmark demonstrate that both the robustness and the timeliness of the proposed tracker are promising when the appearance of the target changes containing translation, rotation and scale or the interference containing illumination, occlusion and cluttered background. Unfortunately, it is not robust enough when the target moves fast or the motion blur and some similar objects exist.","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116368610","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}

In this paper, an effective tracking loop for chirp spread spectrum communication is proposed, which can realize chirp signals modulated by binary phase shift keying (Chirp-BPSK) coherent demodulation with particular Doppler shifts and dynamics, while the bit error rate (BER) is same with the binary phase shift keying (BPSK). First, we design an updated chirp delay locked loop (CDLL) for the chirp signal, and then analyze the performance of the tracking loop such as the pull-in range, measurement errors of CDLL and the carrier loop. Theoretical analysis and simulations demonstrate that the CDLL measurement error is close to the Cramer-Rao lower bound (CRLB) while the carrier tracking loop measurement error is close to the theoretical thermal noise jitter. Finally, BER performance of Chirp-BPSK, with exploiting the proposed loop, increases more than 3dB compared with chirp signals modulated by binary orthogonal keying (Chirp-BOK).","PeriodicalId":234499,"journal":{"name":"2016 IEEE 13th International Conference on Signal Processing (ICSP)","volume":"312 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115444424","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}
