It is known that HRTFs contain spatial cues allowing individuals to localize sounds. Inter-aural phase and level differences, and high-frequency magnitude variations, are among the most common cues. While these cues require detailed analysis of specific HRTFs, in the current paper a new measure is proposed, based on the distribution of the singular values of the HRTF matrix, effectively representing the amount of information contained in the HRTFs as a function of frequency and arrival direction. This measure is generic, encompassing all cues in a single quantity. First, the validity of the proposed measure is justified theoretically. Then, the proposed measure is validated against empirically known results of human localization in the horizontal and median planes. The comparison is performed by taking into account two different aspects: (1) whether the information contained in the HRTFs is monaural or binaural, and (2) the variation of the minimum audible angle (MAA) and other localization measures as a function of azimuth and elevation. The results show that the proposed measure is in good agreement with the established theory of human sound localization and can be used as a predictor of the potential performance of human sound localization and of human-like systems such as humanoid robots.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122395107","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 addition to 4×4 and 8×8 transforms utilized in earlier video coding standards, the proposed HEVC standard suggests the use of larger transform sizes including 16 × 16 and 32×32 transforms in order to obtain higher coding gains. Further, it also proposes the use of non-square transform sizes as well as the use of the discrete sine transform (DST) in certain intra-prediction modes. The decision on the type of transform used in a given prediction scenario is dynamically made, to obtain required compression rates. This motivated the proposed digital VLSI architecture for a multitransform engine capable of computing 16×16 approximate 2-D DCT/DST transform, with null multiplicative complexity. The relationship between DCT-II and DST-II is employed to compute both transforms using the same digital core, leading to reductions in both area and power. Closed-form relationship between the 16×16 transform and arbitrary smaller sized transform is presented, enabling the usability of this architecture to compute transforms of size 4 · 2P × 4 · 2q where 0 ≤ p, q ≤ 2.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132346412","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}

A particular application of this algorithm is the identification of a physical danger to babies, such as situations in which parents leave their children in vehicles. The proposed algorithm is based on two main stages. The first stage involves feature extraction, in which pitch related parameters, MFC (mel-frequency cepstrum) coefficients and short-time energy parameters are extracted from the signal. In the second stage, the signal is classified using the k-NN algorithm and is later verified as a cry signal, based on the pitch and harmonics information. In order to evaluate the performance of the algorithm in real world scenarios, we checked the robustness of the algorithm in the presence of several types of noise, and especially noises such as car horns and car engines that are likely to be present in vehicles. In addition, we addressed real time and low complexity demands during the development of the algorithm. In particular, we used a voice activity detector, which disabled the operation of the algorithm when voice activity was not present. A database of baby cry signals was used for performance evaluation. The results showed good performance of the proposed algorithm, even at low SNR.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134410594","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}

These energies are typically computed as the integral of electrical pulses generated the interaction of Gamma photons with a known semiconductor detector. Due to the finite resolution of the detector, close electrical pulses tend to overlap; this phenomenon, known by the practitioner as pileup effect, yields a severe distortion of the energy spectrum. We present in this contribution a method for pileup attenuation, in order to correct the main distortions caused by the pileup effect. This method can be decomposed in two steps. First, we compute a sparse representation of the signal by means of LASSO in order to estimate the arrival times of each individual electrical pulse and the radioactive source activity. The second step consists in estimating the pulse individual energies by means of another iteration of LASSO, with a smaller value of its sparsity parameter, and plug the obtained values into a standard nonparametric kernel estimator to obtain a corrected energy spectrum. We illustrate the performances of the suggested approach on signals stemming from a High Purity Germanium detector, with a medium activity.","PeriodicalId":177385,"journal":{"name":"2012 IEEE 27th Convention of Electrical and Electronics Engineers in Israel","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133393609","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}
