Efficient BOF Generation and Compression for On-Device Mobile Visual Location Recognition
Found in: IEEE MultiMedia
By Tao Guan,Yunfeng He,Liya Duan,Jianzhong Yang,Juan Gao,Junqing Yu
Issue Date:April 2014
pp. 32-41
Existing mobile visual location recognition (MVLR) applications typically rely on bag-of-features (BOF) representation, which shows superior performance in retrieval accuracy. However, although the BOF framework is promising, it is not compact enough for o...
Real-Time Camera Pose Estimation for Wide-Area Augmented Reality Applications
Found in: IEEE Computer Graphics and Applications
By Tao Guan, Liya Duan, Junqing Yu, Yongjian Chen, Xu Zhang
Issue Date:May 2011
pp. 56-68
Achieving accurate registration between real and synthetic worlds is one of augmented reality's biggest challenges. A real-time camera-pose estimation method, based on multiple maps and local bundle adjustment, enables the registration to work without prio...
