Omni-directional Multi-view Image Measurement System in the Co-sphere Framework

Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 2, Page # 64–70, 2023; DOI: 10.25046/aj080207
Abstract:

This study presents an “Omnidirectional multi-view image measurement system”, which can be used to provide multi-camera 3D reconstruction and multi-view image information. Its characteristic is that four cameras take images from multiple perspectives in the co-sphere framework. The C0 is the middle camera fixed as the geometric center point of measurement, and provides a front…

The Effectiveness of Personality-Based Gamification Model for Foreign Vocabulary Online Learning

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 2, Page # 261–271, 2020; DOI: 10.25046/aj050234
Abstract:

Currently, there is a growing interest for applying gamification in e-learning due to innovations in technologies and pedagogies. However, motivation and engagement related problems can arise when the gamification elements are not personalized to match the individual’s needs. Therefore, this research proposes a Hybrid Learning Model that combines both Gamification and Personality Traits to increase…

Pixel-Based Unsupervised Classification Approach for Information Detection on Optical Markup Recognition Sheet

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 4, Page # 121–132, 2017; DOI: 10.25046/aj020417
Abstract:

This paper proposed an Optical Markup Recognition (OMR) system to be used to detect shaded options of students after MCQ-type examinations. The designed system employed the pixel-based unsupervised classification approach with image pre-processing strategies and compared its efficiencies, in terms of speed and accuracy, with object-based supervised or unsupervised classification OMR systems. Speed and accuracy…

Optimized Multi-focus Image Fusion Using Genetic Algorithm

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 1, Page # 51–56, 2017; DOI: 10.25046/aj020106
Abstract:

Optical imaging systems or cameras have a convex lens with limited depth of field. So, multi-focus images are obtained when such systems are used to capture an image of a particular scene. These images are fused to get all-in-focus image. This paper proposes a new simpler method of multi-focus image fusion. Instead of decomposing input…
