The paper also proposes a method to extract the speech polarity information using the properties of the Hilbert transform. The Hilbert transform of the speech is computed as the imaginary part of the complex analytic signal representation of the original speech. The Hilbert envelope (HE) is then computed as the magnitude of the analytic signal. The average slope of the signal amplitudes of speech and Hilbert transform of speech around the peaks in the HE are observed to be varying in accordance with the polarity of the speech signal. The effectiveness of the proposed approach is confirmed by the performance evaluation over 7 voices of the phonetically balanced CMU-Arctic database and German emotional speech database. The performance of the proposed approach is also observed to be comparable with that of the existing algorithms such as residual skewness based polarity detection and Hilbert phase based speech polarity detection. Finally, a significant improvement in the identification accuracies of the estimated epochs in speech using the popular zero frequency filtering (ZFF) method is demonstrated as an application of the speech polarity detection.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115855218","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 a similar spirit, in this paper, we propose an agri-advisory system developed for analysis of agricultural images, particularly apple images. The image processing tasks considered, are those of super-resolution (SR) and image segmentation for annotation. We develop simple and efficient methods for enhancing the resolution of images, and to automatically segment defects on apples in their images. We propose an example-based SR, which involves simple modules of construction of dictionaries based on local luminance variance, patch selection and weighted reconstruction of patches. The image segmentation algorithm is a combination of chrominance thresholding and low-level morphological operations. Our experimental results demonstrate that such simple and efficient methods suitable for network applications, are also quite effective, given a specific application domain.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122244728","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 proposed method is aimed at reducing the requirement of on-board memory, station contact time and data archival volume. Compressive sensing (CS) has been applied to encode the distributed wavelet coefficients into linear measurements. Since prior knowledge of the compressively sampled measurements is not available, a modeler is employed to determine the context of the measurement vector. Based on the statistics provided by the context modeler, the samples are entropy coded for transmission. A part of the compressive sampling measurements with near uniform distribution are encoded through adjusted binary coding, and the rest are encoded through Golomb-Rice coding. Run length encoding is implemented for exploiting the redundancy in the binary data further. At the receiver end, the original spatial signal is reconstructed from the CS samples by approximate message passing (AMP) algorithm and inverse discrete wavelet transform (IDWT) for video decompression. Simulation of the proposed approach has demonstrated an efficient compression of the video cubes with lower complexity at the transmitter end.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129358119","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, a multi resolution non negative matrix factorisation (NMF) based acoustic echo cancellation method is proposed. This acoustic echo cancellation addresses two important research issues. Unlike conventional filter based algorithms for acoustic echo cancellation, which suffer from poor tracking of time varying loudspeaker microphone enclosure (LEM), this method cancels acoustic echo without estimating the LEM. So it is more robust to both double-talk and single talk scenarios. Secondly, the NMF based acoustic echo cancellation method suffers degeneration of speech signal due to fixed time frequency resolution. The use of adaptive multi-resolutions reduces this degeneration and provides a better estimate of near end speech signal. Experiments on acoustic echo cancellation are performed on CMU ARCTIC database with several datasets at different values of echo to near end signal ratio. The experimental results are compared with existing state of the art echo cancellation methods using both perceptual and objective quality evaluations. The proposed method performs reasonably better than other methods motivating its use in acoustic echo cancellation in teleconferencing environment.","PeriodicalId":279637,"journal":{"name":"2016 Twenty Second National Conference on Communication (NCC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121472202","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}
