However, the conventional similarity calculation may produce inaccurate results because of data sparsity. To alleviate this problem, this paper proposes a new method of similarity calculation based on item rating and genre. Firstly, similarity calculation based on item rating are proposed, which reduces similarity between items with fewer co-rating users. Genre information is an inherent attribute of an item which could not be changed by user behavior. It reflects the common characteristics among items, then item similarity based on the item’s dependency on genre are calculated. Finally, a trade-off between rating and genre similarity are proposed to calaulate the similarity between items. Experimental results show that the proposed method can alleviate the issue of inaccurate similarity caused by sparse data and improve the recommendation quality.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615975","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 the proposed method, the input endoscopic image is converted into the hue-saturation-value color space, and the S space image is used. The pattern of the abnormal area is learned from this image using Daubechies 2 (db2) wavelet lifting wavelet transform. The lifting wavelet transform is performed on the detected image using the learned filter. Each frequency component is obtained using this method. The detected image generated from the sum of the high-frequency components is divided into small blocks. A static threshold is determined herein to obtain a binary image. Discrete wavelet transform is used to exclude smooth areas. V space images are used to exclude dark areas, such as shadows. This emphasizes the contour of the abnormal part. Finally, from the idea that the area surrounded by the outline is also abnormal, the life game is limitedly applied to emphasize the abnormal area. We describe the feature extraction in detail and present the experimental results demonstrating that our method is useful for the development of dysplasia detection from an endoscopic image.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122644489","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 study uses the bispectral analysis technique to process BPE signals for the first time and extracts the high-order spectrum distribution characteristics of normal wheat and infected wheat. By estimating the bispectrum, the slice bispectrum, and the characteristic parameters of the diagonal slice spectrum and the horizontal slice spectrum, the bispectral distribution characteristics of the spontaneous BPE signal of normal wheat and wheat that has been infected by insects are obtained. Bispectral analysis can not only eliminate the interference of Gaussian noise, but also elucidate the amplitude and phase information of the signal. Experiments show that the extracted parameters of the BPE signals yield a detailed spectral distribution and show differences between infected wheat and normal wheat. The results of this study provide a comprehensive description of the characteristics of infected wheat and provide an experimental and theoretical basis for the detection of insects in grain.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133770995","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}

NTP is an image representation method in which the bivariate polynomials are calculated and used to represent the pixel values in each triangular region under a set control error. The number of triangles in each $8times 8$ region is counted and recorded as a feature matrix which will be mapped to a binary watermark scrambling by the Arnold scrambling method to enhance the security of the algorithm. The feature matrix and the scrambled binary watermark are stored as zero watermarks. Experimental results show that the proposed algorithm is robust to various attacks, such as JPEG compression, rotation, Gaussian noise and salt and pepper noise.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114892594","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 order to address this problem, in this paper, a novel approach named wavelet transform-based one dimensional manifold embedding (WT1DME) is proposed for HSI classification. In the proposed approach, firstly, using wavelet transform decomposes the input signal into an approximate coefficients (ACs). Then, smooth ordering is applied to the ACs which maps the coefficients into one-dimensional (1-D) space. Finally, since the coefficients in the 1-D space, hence, 1-D signal processing tools can be applied to build final classifier(we utilize interpolation in this paper). Our proposed methods can be used to process the decompose coefficients in 1-D space, which can perform efficiently. The proposed scheme is experimentally demonstrated by two HSI data sets: IndianPines, University of Pavia has the state-of-the-art performance of results.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117132898","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}

Conventional methods of recognizing a character including Support Vector Machine (SVM) and neural network require the training using many license plate images. However, the amount of training data is limited and there are many unseen situations, where the generalization capability of a trained classifier is usually limited. If the license plate image distortion is serious due to either weather conditions or technical reasons of photographing, accuracy of these methods will be greatly reduced. Therefore a robust license plate recognition method is proposed using a Radial Basis Function Neural Network (RBFNN) trained via a minimization of the localized generalization error model (L-GEM). The L-GEM provides the upper bound of the generalization capability of an RBFNN with respect to a given training data set. Therefore, the trained RBFNN yields a better generalization capability and a higher recognition rate for new unseen samples. Experimental results show that RBFNNs trained by minimizing the L-GEM always yield the highest accuracy in diversified situations, such as rainy and snowy conditions.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128556888","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}
