More specifically, we explore the use of existing objective quality and intelligibility metrics, applied directly to vocoded speech degraded by room reverberation, here assessed at ten different reverberation time (RT60) values: 0 s, 0.4 s - 1.0 s (0.1 s increments), 1.5 s and 2 s. Eight objective speech intelligibility predictors (SIPs) were investigated in this study. Of these, two were non-intrusive (i.e. did not require a reference signal) audio quality measures, four were intrusive, and two were intrusive speech intelligibility indexes. Three types of vocoders were implemented to examine how speech intelligibility predictions depended on the vocoder type. These were: noise-excited vocoder, tone-excited vocoder and a FFT-based N-of-M vocoder. Experimental results show that several intrusive quality and intelligibility measures were highly correlated with exponentially fit CI intelligibility data. On the other hand, only a recently - developed non-intrusive measure showed high correlations. These evaluations suggest that CI intelligibility may be accurately assessed via objective metrics applied to vocoded speech, thus may reduce the need for expensive and time-consuming listening tests.","PeriodicalId":248763,"journal":{"name":"2012 11th International Conference on Information Science, Signal Processing and their Applications (ISSPA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115125401","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}

Effective segmentation requires domain knowledge or strategies for object designation as no universal segmentation algorithm exists. In this paper, we propose a holistic framework to perform image segmentation in color space. Our approach unifies the linear smoothing filter, a similarity calculation in selected color space, and a clustering game model with various evolution dynamics. In our framework, the problem of image segmentation can be considered as a “clustering game”. Within this context, the notion of a cluster turns out to be equivalent to a classical equilibrium concept from game theory, as the game equilibrium reflects both the internal and external cluster conditions. Experiments on image segmentation problems show the superiority of the proposed clustering game based image segmentation framework (CGBISF) using both the Berkeley segmentation dataset and infrared images (for which, we need to perform color fusion first) in autonomy, speed, and efficiency.","PeriodicalId":248763,"journal":{"name":"2012 11th International Conference on Information Science, Signal Processing and their Applications (ISSPA)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127279351","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 enrollment and test procedures are realized in software, while the recognition is implemented in real time on an embedded platform. It uses the wearable Vitalsens wireless sensor with ECG electrodes placed on the chest of the person to be identified, the ECG sensors communicate via Bluetooth with the LM058 Bluetooth adapter connected to the RS232 interface of the RC10 Field Programmable Gate Array (FPGA) prototyping board. A new human identification method based on the fiducial independent feature extraction from ECG signals is implemented on the low power Spartan 3L FPGA chip available on the board. The Principal Component Analysis (PCA) is exploited to select the main significant features. The projected ECG signals on the principal components are then compared by using the Euclidian distance metric. By occupying just the 45% of logic resources and 75% of the BRAM blocks, the embedded system reaches an identification accuracy of 90%.","PeriodicalId":248763,"journal":{"name":"2012 11th International Conference on Information Science, Signal Processing and their Applications (ISSPA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131960320","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}
