깊이 정보 확장과 메쉬 구성을 이용한 DIBR 기반 다시점 중간 영상 화질 향상 방법에 관한 연구

Abstract

ABSTRACT In this research, we conducted an experiment on evaluating the extending depth information method and surface reconstruction method and the interaction of these two methods in order to enhance the final intermediate view images, which are acquired using DIBR (Depth-Image-Based Rendering) method. We evaluated the experimental control groups using the Microsoft’s “Ballet” and “Break Dancer” data sets with three different hole-filling algorithms. The result revealed that the quality was improved the most by applying both extending depth information and surface reconstruction method as compared to the previous point clouds only. In addition, it found that the quality of the intermediate images was improved vastly by only applying extending depth information when using no hole-filling algorithm. 키워드 : 깊이 영상 기반 렌더링, 메쉬 구성, 깊이 정보 확장, 다시점 디스플레이 Key word : Depth-Image-Based Rendering, Mesh Construction, Extending depth information, Multiview DisplayJournal of the Korea Institute of Information andCommunication Engineering
