Developing an automatic system, we employ image processing techniques coupled with graph cut algorithms from combinatorial optimization. Avoiding the need of manual pre-segmentation for constructing an initial graph, a supervised learning approach is effectively and efficiently applied. Crucial information is extracted from a set of labeled binary masks and integrated into weight assignments of the edges of the graph. We associate the characteristically bell-shape of a Gaussian distribution with the rounded circular-shape of the optic disc. Our approach was validated and evaluated on the RIM-ONE open database. Segmentation is successful on 91.12% of the entire 169 images, achieving 91% sensitivity and 88% accuracy.","PeriodicalId":6460,"journal":{"name":"2017 14th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"9 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87778457","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}

We compared two algorithms for analyzing movement trajectories; Sparse code and Incremental Dynamic Time Warping (IDTW). Experimental results show that the methods have an encouraging performance. When comparing the accuracy of algorithms, IDTW gave better recognition results than the Sparse code method.","PeriodicalId":6460,"journal":{"name":"2017 14th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"57 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85646551","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 flow of the information is largely a one-way passive communication due to a lack of user-content interaction, which in some ways limits its effectiveness as an information display system. We propose a use of mobile phones as a tool to interact with a public display. Our proposed mobile-public display user interaction uses a mobile phone to control and retrieve information from a public display. In this paper we present results of a usability test of our proposed interaction, which indicated that there was a strong correlation between the information retrieval performances and the participant's level of engagement with the mobile phone.","PeriodicalId":6460,"journal":{"name":"2017 14th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"15 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72912768","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}

Unfortunately, with its great popularity and a great number of users, spams are also increasing. A number of Facebook services do not require spam detection, whereas the group usage does. Group users are generally those who are interested in the same topics or purposes. Members usually share the contents of interest in the group. These characteristics enable detection of unwanted posts, referred to as spam that annoys others. It should be noted that some spam may jeopardize the group, for example, by malicious URLs. The objective of this article is to present the design concept for detecting spam in closed groups by using the combination of text features and social features, which comprised 11 features for classifying spam by applying Random Forest machine learning algorithm on 1,200 labeled posts. The result indicated 98% of spam detection efficiency. Additionally, from the feature importance, the number of likes, one of the social features, was found to be the most effective for spam detection.","PeriodicalId":6460,"journal":{"name":"2017 14th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"91 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86751734","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}

It allows a shape to be recognized based on automatically located outstanding local features on its contour, which are extracted from 1-D signal representations of different smoothing scales. The algorithm describes each local feature as a list of frequencies from curvature histogram, which is created from curve segment around each local position. The descriptors will give high similarity compared with a model descriptors of a similar shape. The algorithm has properties of image scaling-, translation-, and rotation-invariants. An experiment were conducted with 200 images from Flavia dataset for verification.

Since a specification is created as the business requirement and a program should have functioned as in the specification, the formal verification is needed to assure the correctness of the function in the program. Both an ABAP program and its specification are translated into Z specification and they are verified by Isabelle in order to ensure that the ABAP program conforms to its specification.

This paper utilizes two popular algorithms: collaborative based recommendation using Pearson Correlation Coefficient and Alternating Least Square (ALS), and compares their performance on a dataset of academic records of university students.
