Methods: This paper proposed a texture analysis method based on statistical contourlet coefficient (SCC) to extract the quantitative features of regions of interest (ROIs) in non-enhanced CT images. The SCC method consisted of two steps. First, it decompose an ROI into several subbands at multiple directions in multiple layers, where a \"9-7\" filter was applied in the Laplacian pyramid filtering stage and a \"pkva\" filter was applied in the directional filtering stage. Then, it performed normalization on the coefficient matrices of the subbands and extracted the first and second order statistical features of the normalized matrices. Six traditional texture analysis methods that are widely used for medical image processing were used for comparisons. After the feature extraction, feature selection and classification (10-fold cross training and test) were performed, and the classification results were evaluated. Results: The proposed method achieved the best classification result: the average accuracy was 79.52%; the average sensitivity was 78.5%; the average specificity was 80.63%; the average AUC was 0.848. Conclusions: It indicates that the texture analysis method based on statistical contourlet coefficient is rewarding for computer-aided diagnosis of pancreatic cancer and normal pancreas using non-enhanced CT images. It can reduce the workload of radiologists and play a significant guiding effect on junior radiologists.","PeriodicalId":370976,"journal":{"name":"Proceedings of the International Symposium on Big Data and Artificial Intelligence","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122023569","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 context of the \"Internet\", the development of network technology has made mobile payments also considered by consumers to be included in offline payments. On the basis of previous studies, the paper analyzes and summarizes 10 factors influencing consumers' choice of offline mobile payment. Taking students and office workers as examples, the technology acceptance model is used to verify and analyze hypotheses. The results of the study show that perceived risk does not have consumer perceived usefulness, perceived risk, subjective normative questions, perceived ease of use, questions about consumer innovation, willingness to use, and experience of heart flow. Questions such as questions about the use behavior, questions about self-image, and questions about self-efficacy have a positive effect on the willingness to use. The results of the study were analyzed and corresponding recommendations were made.","PeriodicalId":370976,"journal":{"name":"Proceedings of the International Symposium on Big Data and Artificial Intelligence","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129410816","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}

Therefore, in order to improve the measurement accuracy of the detector, reduce the effect of temperature on the pH measurement of the solution, simplify the circuit layout, and enhance the stability of the measurement circuit, Developed a STC89C52 microcontroller as the core processor, using Raycore E-201-CPH composite electrode to collect analog voltage signal and transfer it to A/D converter to convert into digital signal after amplified by op amp, and input it into the single-chip microcomputer together with the digital signal collected by the temperature sensor. Finally, after processing by the SCM, it is transmitted to the LCD1602 liquid crystal display module, showing the measured pH value and temperature value. The whole design is made down, and after many debugging, it can be concluded that the PH detector can accurately detect the PH value of the solution. It also has the characteristics of cheaper, affordable, high precision, good stability, simple circuit, simple operation and so on, which is suitable for the needs of most of the current users.","PeriodicalId":370976,"journal":{"name":"Proceedings of the International Symposium on Big Data and Artificial Intelligence","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124535991","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}
