Yueh-Cheng Huang, Hsin-Yi Chen, Cheng-Jui Hung +2
Confronting the critical challenge of insufficient training data in the field of complex image recognition, this paper introduces a novel 3D viewpoint augmentation technique specif…
Equivalence of Two Expressions of Principal Line
Cheng-Yen Hsu, Hsin-Yi Chen, Jen-Hui Chuang
Geometry-based camera calibration using principal line is more precise and robust than calibration using optimization approaches; therefore, several researches try to re-derive the…
Visualizing and Alleviating the Effect of Radial Distortion on Camera Calibration Using Principal Lines
Jen-Hui Chuang, Hsin-Yi Chen
Preparing appropriate images for camera calibration is crucial to obtain accurate results. In this paper, new suggestions for preparing such data to alleviate the adverse effect of…
Descriptor Ensemble: An Unsupervised Approach to Descriptor Fusion in the Homography Space
Yuan-Ting Hu, Yen-Yu Lin, Hsin-Yi Chen +2
With the aim to improve the performance of feature matching, we present an unsupervised approach to fuse various local descriptors in the space of homographies. Inspired by the obs…
