Shape-Based Plagiarism Detection for Flowchart Figures in Texts
Plagiarism detection is well known phenomenon in the academic arena. Copying
other people is considered as serious offence that needs to be checked. There
are many plagiarism detection systems such as turn-it-in that has been
developed to provide this checks. Most, if not all, discard the figures and
charts before checking for plagiarism. Discarding the figures and charts
results in look holes that people can take advantage. That means people can
plagiarized figures and charts easily without the current plagiarism systems
detecting it. There are very few papers which talks about flowcharts plagiarism
detection. Therefore, there is a need to develop a system that will detect
plagiarism in figures and charts. This paper presents a method for detecting
flow chart figure plagiarism based on shape-based image processing and
multimedia retrieval. The method managed to retrieve flowcharts with ranked
similarity according to different matching sets.Comment: 12 page
Hybrid markerless augmented reality tracking method for planar surface
Markerless tracking for augmented reality should not only accurate but also fast enough to provide a seamless synchronization between real and virtual beings. Current methods showed that a vision-based tracking is accurate but requires high computational power. This paper proposes a real-time hybrid-based method for tracking unknown environments in markerless augmented reality. The proposed method provides collaboration of vision-based approach with accelerometers and gyroscopes sensors as camera pose predictor. To align the augmentation relative to camera motion, the tracking method is done by substituting feature-based camera estimation with combination of inertial sensors with complementary filter to provide more dynamic response. The proposed method managed to track unknown environment with faster processing time compared to feature-based approach. Moreover, the proposed method can sustain its estimation in a situation where feature-based tracking loses its track. The collaboration of sensor tracking managed to perform the task for about 22,97 FPS, up to five times faster than feature-based tracking method used as comparison. Therefore, the proposed method can be used to track unknown environments without depending on amount of features on scene, while requiring lower computational cost
