Online Approximate Model Representation Based on Scale-Normalized and Fronto-Parallel Appearance
Various object representations have been widely used for many tasks such as object detection, recognition, and tracking. Most of them requires an intensive training process on large database which is collected...

Degeneracy of the Linear Seventeen-Point Algorithm for Generalized Essential Matrix
In estimating motions of multi-centered optical systems using the generalized camera model, one can use the linear seventeen-point algorithm for obtaining a generalized essential matrix, the counterpart of the...

Semi-metric Space: A New Approach to Treat Orthogonality and Parallelism
We propose a new method to recover 3D structures of artificial objects from scene pictures using orthogonality and parallelism. A new transformation group, “semi-metric space,” is defined to describe the scene...

Infinite Homography Estimation Using Two Arbitrary Planar Rectangles
In this paper, we propose a new method to estimate an infinite homography between two views containing two arbitrary planar rectangles. The proposed method does not require metric measurements, such as rectang...
