The system provides the user with the score that was assessed by acoustic features and the rhythmic similarity between the original song and the user input. The assessment system is divided into two stages. In the first stage, acoustic similarities are measured by dynamic time warping (DTW). In the second stage, the rhythmic similarity is measured by analysing the optimal path of DTW by quadratic polynomial regression. Finally, the similarity of two stages is combined into one score by corresponding weights. The experimental results show the good performance for the automatic singing evaluation system.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126263093","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 work, first, the heart sounds (normal and abnormal) are decomposed by complementary ensemble empirical mode decomposition (CEEMD). Next, first five subcomponents are chosen empirically for further process. The instantaneous characteristics including instantaneous energy (IE) and frequency (IF) are estimated using Teager energy operator (TEO). After that, disregarding the energy and frequency information, total five IE versus IF maps are constructed. Then, the five IE-IF values transferred into a single feature space and using K-means algorithm, five mean values are selected. Further, a code book is constructed by vector quantization (VQ) method for the learning and future reference purpose. The experiment is performed on total 23 different classes of heart sounds including the normal and abnormal cases, collected from the Michigan Heart Sound and Murmur Database. The results indicate that the proposed method can achieve a recognition rate of 98%. Furthermore, a comparison with previous methods reveals that the proposed approach is superior. In contrast, the method is totally independent of any prior assumptions.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"291 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116243177","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}

Each frame of noisy speech signal is sparsified firstly by using discrete cosine transform (DCT). Then we divide each frame into the noisy sub-frame and the clear sub-frame with a soft thresholding method to obtain the threholded DCT coefficients of the noisy sub-frames. After that, the partial Hadamard ensemble is used as a sensing matrix to achieve compressive measurement of the DCT coefficients of noisy sub-frame. Finally, We use the orthogonal matching pursuit in order to recover the de-noised speech signal from noisy sub-frame. Both objective and subjective experiments are employed to compare the proposed approach with the subspace method and the spectral subtraction method. Experimental results shows that proposed method outperforms other methods with the highest PESQ, ABX and MOS score for Gaussian white noise and most kinds of colour noise.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134487082","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 color attention is represented by the fast calculated color descriptor on color names, which is used to weight the similarity measurement of the sparse generative model. In the sparse generative model, the image region of the object is divided into patches. And we take into consideration of the spatial information of each patch to handle the occlusion. The color attention assists the sparse generative model to match the spatial structure of the object and handle illumination variation and heavy occlusion on the object. The update scheme considers both the original template and the latest observations, which enables the tracker to deal with appearance change effectively and alleviate the drifting problem.

Finally, the normalized threshold method is adopted to measure the smile intensity. The experimental results have shown that the proposed approach can achieve an average accuracy rate of 80% for the smiling measuring with four different levels of intensity.

In order to detect the indoor wandering of demented elders living alone in real time, this paper proposes a light-weight wandering detection system named LWDS. Specifically, the LWDS system first collects the location information with timestamp using a pair of pyroelectric infrared sensors mounted on the doors of each room, and then classifies the ongoing trajectory consisting of a series of locations into different wandering locomotion patterns according to an established wandering model. After a trajectory has been detected as containing wandering behavior, the developed system will send an alert to their carers for necessary treatment. The non-intrusive and easy-to-deploy properties ensure the proposed LWDS system can find wandering behaviors in a cost-effective and energy-efficient manner around the clock. An experimental evaluation conducted on a group of real data collected from two elders showed that the LWDS is effective in detecting indoor wandering when they moved across different rooms and obtained a detection ratio of more than 90.03% for the wandering patterns.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129144576","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 amplitude and delay of the output pulse are based on the degree of the mismatch. An algorithm of Doppler frequency estimation is proposed basing on the amplitude of the output pulse. The algorithm sets a group of matched filters whose middle frequencies increase in an established pattern. When the echo pulse goes through them, the outputs will appear in different amplitudes and delays. The Doppler frequency is calculated by the two pulses whose amplitude is the biggest. The delay of echo will be compensated by the estimated Doppler frequency, which may achieve the target's precise location. Compared to standard processing of matched filtering, this algorithm dosen't cost more time. In addition, the Hyper-Rayleigh limit estimation can be achieved in the condition of a appropriate signal-to-noise ratio (SNR). The principle is discussed in this paper, and the simulation illustrates the feasibility and effectiveness of the algorithm.","PeriodicalId":343641,"journal":{"name":"2014 International Conference on Orange Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131625691","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}
