Principal component analysis (PCA) is able to extract data's independent features on the basis of the second-order statistics, the variational Bayesian independent component analysis (VBICA) not only overcome the inconsistency between the standard ICA model and remote sensing image but also decrease the computational complexity. In view of the characteristics of high-resolution remote sensing, a thematic information extraction method based on weighted PCA and VBICA is presented in this article, and IKONOS high-resolution remote sensing image experiments are performed.

An efficient two-step detection framework is proposed in this paper to detect oil depots in high resolution remote sensing images. In the first stage, LC saliency model is used to detect the salient regions and shows a good performance on highlighting oil depots. In the second stage, task related targets from these salient regions are extracted by removing the irrelevant salient areas according to the special properties of the targets. According to the final shape, the area and distribution of oil depots, using image threshold segmentation and the graph-based clustering procedure, oil depots are detected with fairly good accuracy and efficiency.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132070606","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 applications may run on the same MapReduce cluster, with their own system-wide configure settings and library dependencies, respectively. Sometimes, their configure settings and library dependencies are conflicted with each other. How to ensure these applications to run together correctly without mutual interference and achieve high resources utilization gives a challenge to the researchers. In this paper, we propose DCSpark, a framework that leverages the power of Docker containers that allows users to run Spark applications which have conflicting configurations and library dependencies in one physical cluster. In addition, it's presented an implementation of our framework called DCM which is aimed at managing the physical cluster, processing scheduling problem and building the container-based Spark cluster images automatically according to the dependence environment of the applications. Our experimental evaluation shows that DCSpark introduces negligible overhead for CPU and memory performance compared with the native Spark cluster.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130808968","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 Experiment 1, The participants were asked to perform the task of language-switching between their two dissimilar but highly proficient languages (Tibetan-Mandarin) ,in which they had to name the pictures quickly and accurately by using the cued language in the picture-word interference paradigm. In Experiment 2 and 3, the partcipants finished the same tasks except that they switched the languages between a more-proficient language (Tibetan or Mandarin) and dissimilar and less proficient language (English). The results showed there was no asymmetrical switching cost between Tibetan and Mandarin; and there was asymmetrical switching cost between non-fluent and proficient languages; meanwhile, language similarity affected speech production for non-proficient bilinguals. The results suggested that language similarity may play a role in the lexical selection mechanisms used by highly proficient bilinguals.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949951","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}

Most of the point cloud matching without landmark used the iterative closest point algorithm. In order to improve the performance of the iterative closest point algorithm, the two-step iterative closest point algorithm was proposed. The improved algorithm is divided into a rough matching step and accurate matching step. Rough matching used the principal component analysis algorithm, while the fine matching used the improved iterative closest point algorithm. Compared with the classic iterative closest point algorithm, the improved algorithm can match the partial coincident point cloud. At the same time, the experiment can validate the effectiveness of the proposed algorithm.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131730701","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}

Different from traditional coding schemes in which distortion mainly comes from quantizer, distortion are related to quantization and compressive sampling in compressive sensing based coding schemes. Since the total coding bits are often constrained in the practical application, it is a great challenge to balance the number of measurements and quantization parameter to minimization the distortion. In this paper, a source rate and distortion model is proposed. The accuracy of the proposed R-D model is verified through experiments. Based on the R-D model, the optimal number of measurements and quantization step size are determined according to the rate-distortion criteria. Experimental results show that the proposed algorithm improves coding performances substantially.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"4 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129228065","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}

Therefore, higher quality and lower rate speech coding is needed. In order to improve the synthetic speech quality and save channel bandwidth, voice activity detection (VAD) technique is introduced to Mixed Excitation Linear Prediction (MELP) vocoder at 600bps in this paper. It can save channel bandwidth and reduce noise, coding rate and power consumption. In order to improve the accuracy of speech endpoint detection at low signal-to-noise ratio (SNR), noise reduction is adopted to improve SNR, and the VAD algorithm based on statistical model (STAT-VAD) is used. The MELP vocoder with VAD and noise reduction not only has good anti-noise ability and can improve robustness in random channel, but also can reduce the average coding rate and save channel bandwidth. The quality of synthetic speech can achieve the desired results at low SNR. In addition, the vocoder at 600bps with VAD can run in real-time on TMS320VC5510 DSP platform.","PeriodicalId":184170,"journal":{"name":"2016 International Conference on Audio, Language and Image Processing (ICALIP)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125365858","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}
