Therefore, the objective of this study is to develop a robust classification model generated by a genetic-based SVM (GA-SVM) that can automatically determine the optimal parameters of SVM with the highest predictive accuracy and generalization ability. Based on acoustic signals, the energy and entropy are derived as a feature input to the SVM classifier to detect termites. From these experimental results, it can be seen that the GA-SVM can more significantly improve the performance of our proposed system compared to previous research based on the grid-search method.

This paper deals with enhancing the compression ratio by improving the Discrete Cosine Transform (DCT) by taking into account the sign-symbol (result after standard DCT transform); this is done by evaluating the derivative of sample data to determine the DCT matrix improvement. It is shown that our proposed can be embedded into standard DCT coefficients and is compatible with the feature in the video coding. Experiments show that the proposed method gives an improvement in computing requirements and can achieve a reasonable compromise between coding quality and efficiency. It offers no divergence from the H.265/HEVC standards and can be used in current systems.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132907986","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}

Leaf detection in this research used Haar cascade classifier and image processing techniques to automatically detect tobacco leaves in images. The proposed detection algorithm was implemented through OpenCV Python. The Haar cascade classifier was trained with 1,000 images and tested with 150 images. To improve the detection results of the classifier and ultimately detecting tobacco leaves, image processing techniques such as converting RGB to grayscale, blurring, thresholding, and finding connected components were applied. The experimental results show that the classifier can successfully distinguish tobacco leaves from other objects even those having resemblance to the characteristics of tobacco leaves in terms of color and shape. The accuracy rate of at least 91.33% proves the capability of the Haar cascade classifier to detect single and multiple tobacco leaves posed at different angles and taken at different distances from the camera. After applying some image processing techniques, the detection rate reached 100.00% and took 62 ms on average.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128801595","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}

DBT has the potential to overcome the tissue superimposition problems that occur on traditional mammograms for tumor detection. However, DBT generates numerous images, thereby creating a heavy workload for radiologists. Therefore, constructing an automatic computer-aided diagnosis (CAD) system for DBT image analysis is necessary. This study compared feature-based CAD and convolutional neural network (CNN)-based CAD for breast cancer classification from DBT images. The research methods included image preprocessing, candidate tumor identification, three-dimensional feature generation, classification, image cropping, augmentation, CNN model design, and deep learning. The accuracy rates (standard deviation) of the CNN- and feature-based CAD for breast cancer classification were 74.85% (0.122) and 87.12% (0.035), respectively. The T value was -6.229, and the P value was 0.00 < 0.05, which indicated that the CNN-based CAD significantly outperformed feature-based CAD. The results can be applied to clinical medicine and assist radiologists in breast cancer identification.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115878383","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, a deception is a very common phenomenon in speech communication. It is difficult to detect if anyone is actually telling the truth or not. This study proposes a neural response based novel technique to identify the true or false from speech. In this study, the speech signal is used as the input to the auditory nerve model. This technique applies the higher order statistics called bispectrum to the auditory neurogram to distinguish the true and false from speech. Different parameters of the bispectrum are used as a feature to detect a deception from speech. Deceptive speech can be detected accurately by using the 'normalized bispectral entropy' of the bispectrum feature parameters for the envelope information (ENV) data and the 'maximum bispectrum' of the bispectrum feature parameter for the temporal fine structure (TFS) data. Speech based deception detection is a speech processing method which provides better accuracy to detect deception than many other deception detection techniques. This technique could be applied effectively for the national security systems.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131949061","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 Naiver Stocks equations (continuity, energy and momentum) are solved together using PHOENICS software package. The simulation for the liquid model presents the effect of both free and forced convection on the temperature distribution in the liquid food at the beginning of compression. It also shows the effects of the forced convection on the location of Highest Temperature Region (HTR), which is created as a result of the difference between the pumping fluid velocity that leaves the inlet and the treatment chamber velocity. The simulations also show that after the end of the compression process, the heat transfer is in particular controlled by conduction heating which is due to the to the minor influence of natural convection.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114504820","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, most existing supervised methods only used one kind of annotation information, and so they didn't fully and effectively utilize biomedical image information. In this paper, we propose a single, unified salient-regions-based convolutional neural network (SRCNN) to address this challenging task. The proposed SRCNN takes advantage of multi-annotation information (i.e., classification labels and segmentation labels) and combines prior knowledge of cardiologists. Our contributions in this paper are as follows: (i) We employ a bi-branch network combining the annotation information of classification and segmentation to recognize vulnerable plaques in IVOCT images. (2) According to prior knowledge of cardiologists, we construct a salient region proposal network (SRPN) that can propose irregular salient regions different from bounding boxes. (3) We embed SRPN in the bi-branch network through an appropriate merging strategy, and call this new bi-branch network SRCNN. Our proposed SRCNN is evaluated on the 2017 CCCV-IVOCT Challenge dataset. And ablation experiments demonstrate that compared to separate networks, the bi-branch network can improve the performance of classification and segmentation simultaneously. Furthermore, they also show SRPN contributes to extracting more discriminative features and boosting the whole performance of recognizing vulnerable plaques in IVOCT images greatly.","PeriodicalId":324982,"journal":{"name":"Proceedings of the 2nd International Conference on Graphics and Signal Processing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125588176","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}
