According to this regularity, a method for estimating the instantaneous frequency of underwater acoustic signal using wavelet ridges is put forward. Detection experiments of underwater acoustic signal with stable-frequency and the linear frequency modulation are both carried out using wavelet transform, and the results prove the correctness of this method.","PeriodicalId":211273,"journal":{"name":"2014 11th International Computer Conference on Wavelet Actiev Media Technology and Information Processing(ICCWAMTIP)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114409890","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, new image resolution enhancement methods using wavelet packet transform and neural networks are proposed. The input image is decomposed by using wavelet packet transform. In this work, the wavelet packet decomposition sub-images are used to train neural networks. Multilayer Perceptron (MLP) and Radial Basis Function (RBF) neural networks are employed to predict the expected wavelet packet sub-images of a high-resolution image. The super-resolved image is finally produced by using the synthesis procedure of wavelet packet transform. The objective and subjective quality assessments indicate that the proposed methods outperform the conventional image resolution enhancement techniques.","PeriodicalId":211273,"journal":{"name":"2014 11th International Computer Conference on Wavelet Actiev Media Technology and Information Processing(ICCWAMTIP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125495874","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, under the environments with dynamical obstacles, the existing CRLB does not represent the effect of the non-line-of-sight (NLOS) bias caused by dynamical obstacles. In this paper, based on received signal strength (RSS) measurements, a uniform random variable is used to model the NLOS bias effect.
