Abstract: BACKGROUND Current phase mapping systems for atrial fibrillation create 2-dimensional (2D) maps. This process may affect the accurate detection of rotors. We developed a 3-dimensional (3D) phase mapping technique that uses the 3D locations of… read more here.

Abstract: We consider the problem of 2-D phase unwrapping that of reconstructing the absolute phase (up to a constant) given a noisy $2\pi $ -wrapped phase map as input. In particular, we present an algorithm that… read more here.

Abstract: Pixel-by-pixel phase unwrapping (PPU) has been employed to rapidly achieve three-dimensional (3-D) shape measurement without additional projection patterns. However, the maximum measurement depth range that traditional PPU can handle is within 2π in phase domain;… read more here.
