In this study, we made an attempt to clarify the acoustic feature of the death growl and screaming voice. We chose jitter, shimmer and HNR as the acoustic features, and found that the death growl and screaming voice have much larger jitter and shimmer, lower HNR compared with the normal voice. Next, we investigated the relationship between subjective impression and acoustic feature, and found that the screaming voice has an optimum jitter.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126525691","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 has not been widely adopted due to the hardware requirements it imposes. In consequence, very few Ambisonics encoded contents are available. End-users will find it more attractive to invest in Ambisonics systems if they can be made backwards compatible with existing recordings. In this paper, a technique to spatially extrapolate stereo sources for listening using Ambisonics reproduction systems is introduced. The proposed approach makes use of the spatial information already encoded in most modern stereo recordings. This spatial information is usually used to decode multichannel audio signals, such as 5.1 channel surround. Unlike these technologies, the proposal attempts to extract a continuous description of the 360-degrees horizontal sound field which would result in the original stereo recording. The output is encoded using the circular harmonic functions, making it adequate for reproduction using horizontally-distributed loudspeaker arrays.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121786049","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}

Only k out of n shares are generated by random grids, while the other n-k shares are generated by probabilistic visual cryptography technique.

This paper proposes a novel approach of extracting traffic parameters such as time occupancy, volume and vehicle velocity based on video images. Visual features obtained from spatio-temporal images are more immune to environmental variations which including illuminations and background. Also binaryzation with Self-adaptive Threshold based on clustering can segment vehicle areas more accurately. With combination of parameters modification, PVI and EPI analysis serve to extract final parameters even when congestion happens. To testify the efficacy of measurement, extracted parameters are input to classifier of Support Vector Machine (SVM) to identify four levels of traffic states, which are fluent, non-congestion, congestion and terrible congestion respectively. Experimental results show that performance can sustain various environmental conditions and the accuracy is robust in heavy traffic states.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133666291","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}

During self-motion, a short noise burst was presented from one of the loudspeakers aligned parallel to the motion direction when the listener's coronal plane reached a particular location (baseline). The effect of active and passive forward movement on perceived auditory space representation was also investigated. Results showed that the sound position aligned with the subjective coronal plane was displaced compared with the baseline only during forward self-motion. However, the direction of displacement during forward motion differed among experiments. Moreover, no difference was observed between active and passive motion.

The proposed method divides the cover image into some m×n blocks and partitions the binary secret data into some vectors with the length of m*n. For each block, one Hamiltonian path is first found such that the LSB of pixels of the block along this path have the maximum similarity to the corresponding vector of data. Then this part of data is embedded into the first LSB of pixels of the block along the best path using the modified LSB matching and the code of this path is embedded into the second LSB of the pixels using a novel method such that the minimum MSE value between the block of the cover image and the block of the stego-image is achieved. The experimental results evaluated on 8000 natural images reveal that the proposed method produces minimum distortion in the stego-images. Security of our method against one of the most effective steganalyzers is demonstrated.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115458255","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}

This paper proposes an improved compressed-sensing-base wireless video multicast (iCS-WVM) technique, where the measurements of each group of pictures (GOP) are packed and transmitted through an analog channel. Each receiver obtains some packets according to its channel characteristic and then the packets are decoded by exploiting the correlation of the video frames. Due to the fact that measurements from compressed sensing have the same importance, the receiver with good channel will receive more packets so as to recover a better quality, which guarantees iCS-WVM with a graceful degradation rather than cliff effects. Additionally, by exploit the motion estimation at the decoder side, iCS-WCM achieves better rate-distortion performance than the state-of-the-art Soft Cast and PQC, meanwhile a low-complexity encoding is preserved.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124283621","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, we propose a real-time approach to vascular beating modeling, which can be used in virtual interventional simulation system. First of all, we read out the VTK file of vascular model through VTK function. Then, we choose a center point in a small space and structure the mass-spring model between the center point and other points discreted on the vascular model. After that, we give the center point a force to pull other points. Finally, we set a time callback function to give a beating frequency. Thus, the vascular will beat according to human heart beating rate. Our experimental results show that the method is simple and effective, it can also provide a visually plausible vascular beating effect in a real time way. So it can become an important part of virtual interventional simulation system.","PeriodicalId":105427,"journal":{"name":"2013 Ninth International Conference on Intelligent Information Hiding and Multimedia Signal Processing","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116320810","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}
