However, most techniques request a human to identify the portion to be inpainted. We developed a new mechanism which can automatically detect defect portions in a photo, including damages by color ink spray and scratch drawing. The mechanism is based on several filters and structural information of damages. Old photos from the author's family are used for testing. Preliminary results show that most damages can be automatically detected without human involvement. The mechanism is integrated with our inpainting algorithms to complete a fully automatic photo defects repairing system.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920051","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 new multi-level packet scheduling algorithm, MLDDRR, enhanced from the existing dynamic deficit round-robin (DDRR) for the support of delay-sensitive applications. The network operator can simply change the level of service differentiation by adjusting parameters. The MLDDRR can achieve high throughput efficiently and simultaneously provide smaller delay for short packets of each service class. The feature of small delay for short packets is of great importance for improving the playback quality of real-time applications such as VoIP or scalable media stream delivery. Simulation results showing the high effectiveness and small overhead of MLDDRR are also presented.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"315 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120948708","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}

Researches in the last two decades have established the existence of chaos in human voice production. The purpose of this paper is to use nonlinear dynamics methods in the analysis of normal voices from healthy subjects and correlate them to traditional acoustic parameters as well as perceptual analysis. Twelve human voice signals from healthy subjects, 6 males and 6 females, ranging in age from 19 to 39 years old were used. Sustained vowel sounds /a/, /e/ and /i/ if, from Brazilian Portuguese were recorded at a sampling rate of 22,050 Hz and analyzed in order to obtain acoustic perturbation measures (jitter, shimmer, coefficient of excess - EX, and pitch amplitude - PA), The phase space reconstruction method was used to describe the nonlinear dynamic characteristics of voice signal samples. This paper shows that nonlinear dynamical methods as phase space reconstruction seems to be a suitable technique for voice signals analysis, due to the chaotic component of the human voice. The results suggest that non-linear dynamic analysis does not replace existing techniques instead they may improve and complement the recent voice analysis methods available for health professionals, speech therapist and clinician.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128151702","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}

Koh","doi":"10.1109/ISM.2005.111","DOIUrl":"https://doi.org/10.1109/ISM.2005.111","url":null,"abstract":"With the proliferation of broadband access and continuous decline of storage prize per gigabyte, there has been an increasing demand of audio solution that provides high sampling rate and high resolution. Lossless audio is undoubtedly the ultimate solution. In response to this demand, MPEG issued a call for proposal soliciting technology contributions that provides a state-of-art solution. At the technology end, lossless compression requires the usage of integer transform. The integer modified discrete cosine transform (IntMDCT) has been adopted in MPEG-4 scalable to lossless (SLS) coding to enable this efficient lossless operation. Because of rounding operations, rounding errors introduced by IntMDCT exist during the whole coding process. With the SLS having capability of using operations that spreads over the bitrate spectrum which ranges from lossy to lossless, it is of interest to study the effect of rounding errors in IntMDCT for operation of SLS in lossy mode. This paper analyzes the contributions of noise due to these errors. It is found that the noise introduced by rounding operations of IntMDCT does not affect the perceptual quality of the coded audio under any circumstances. As such, it concludes that the MDCT and IntMDCT filterbanks are interchangeable at lossy bitrate. With the fact that SLS uses both MDCT and IntMDCT, the finding in this paper suggests the possibility of using only IntMDCT filterbank.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"296 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132832665","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}

By introducing error resilience and error concealment techniques, many researchers have tried to eliminate quality degradation of reconstructed picture in decoding a corrupted data. On the contrary, there are relatively fewer works discussing the ways to diminish the corruption. Hence, system designers need to use different methods to restrict the error cause by channel within a tolerable extent. In other words, the system will be difficult to be implemented in practical design. In this paper, we propose a way to protect the video header information in application layer without modifying standardized syntax. Beside, we also consider channel condition of wireless transmission and propose a way to reduce redundant bits used in channel coding. By doing this, the bitstream can be simply transmitted over practical wireless network and the reconstructed picture quality outperforms the original one.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134456174","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 proposed and evaluated a scheme that uses SP frames as a mechanism to switch within a single compressed stream for the purpose of achieving error resilience and rate scalability. We have only considered the restricted but practical case in which only one secondary SP frame is allowed for every primary SP frame.

However, variations in channel conditions cause delays and packet erasures resulting in degradation of quality of service (QoS). Multiple description (MD) coding is one method to reduce the detrimental effects caused by these channel variations. In this paper we have presented a novel pre-processing MD approach, which makes use of the redundancies already present in the original sequence to create multiple descriptions. The proposed approach is compatible with the commonly used video coding standards such as the H.26x and MPEG. The proposed scheme improves performance in terms of the coding efficiency and error resiliency compared to the approaches present in the literature.","PeriodicalId":322363,"journal":{"name":"Seventh IEEE International Symposium on Multimedia (ISM'05)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117157087","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}
