This paper proposes a “non-contact virtual clay modeling interface.” We developed a prototype of a three-dimensional modeling system that allows the user to deform the “virt...
—In [1, 2, 3], we have introduced a robust and secure digital signature solution for multimedia content authentication, by integrating content feature extraction, error correctio...
The geometry of plane-based calibration methods is well understood, but some user interaction is often needed in practice for feature detection. This paper presents a fully automa...
In order to reconstruct 3-D shape from two uncalibrated views, one needs to resolve two problems: (i) the computed focal lengths can be imaginary; (ii) the computation fails for fi...
In computed tomography, direct inversion of the Radon transform requires more projections than are practical due to constraints in scan time and image accessibility. Therefore, it...
