2D-to-3D video frame conversion
A wide spread adoption of 3D videos and technologies is hindered by the lack of high-quality 3D content. One promising solution to address this problem is to use automated 2D-to-3D conversion. However, current conversion methods, while general, produce low-quality results with artefacts that are not acceptable to many viewers. Creating a database of 3D stereoscopic videos with accurate depth is, however, very difficult. Computer generated content can be used to generate high-quality 3D video reference database for 2D-to-3D conversion. The method transfers depth information from frames in the 3D reference database to the target frame while respecting object boundaries. It computes depth maps from the depth gradients, and outputs a stereoscopic video. |

Alternating frequency captures for time of flight depth sensing
Time-of-flight (ToF) 3D depth sensors are used virtual and augmented reality (VR/AR) due to their light weight, small form factor, low computation cost and high depth quality.

Charge carrier extraction inverse diode
An inverse diode die is “fast” (i.e., has a small peak reverse recovery current) due to the presence of a novel topside P+ type charge carrier extraction region and a lightly-doped bottomside transparent anode. During forward conduction, the number of charge carriers in the N− type drift region is reduced due to holes being continuously extracted by an electric field set up by the P+ type charge carrier extraction region. Electrons are extracted by the transparent anode. When the voltage across the device is then reversed, the magnitude of the peak reverse recovery current is reduced due to there being a smaller number of charge carriers that need to be removed before the diode can begin reverse blocking mode operation. Advantageously, the diode is fast without having to include lifetime killers or otherwise introduce recombination centers. The inverse diode therefore has a desirably small reverse leakage current. |

Processing method for sector-shaped wafer piece
A sector-shaped wafer piece is processed according to the shape of the piece obtained by dividing a wafer into quarters. Information is collected on the shapes of four patterns of the quarter wafer pieces different in the position of a circular arc of an outer periphery and on processing feed quantities corresponding to the shapes of the four patterns. A pattern is selected by calculating a region of a square having vertical and horizontal sides equal to the two sides of the quarter wafer piece, imaging each of the sides to search for the presence/absence of a target pattern, and selecting that one of the four patterns to which the held quarter wafer piece corresponds. The held quarter wafer piece is processed along division lines with a processing feed quantity corresponding to the selected pattern. |

Method of processing workpiece
A method of processing a plate-shaped workpiece that includes on a face side thereof layered bodies containing metal which are formed in superposed relation to projected dicing lines includes the steps of holding a face side of the workpiece on a holding table, thereafter, applying a laser beam having a wavelength that is absorbable by the workpiece to a reverse side thereof along the projected dicing lines to form laser-processed grooves in the workpiece which terminate short of the layered bodies, and thereafter, cutting bottoms of the laser-processed grooves with a cutting blade to sever the workpiece together with the layered bodies along the projected dicing lines. The step of cutting bottoms of the laser-processed grooves includes the step of cutting bottoms of the laser-processed grooves while supplying a cutting fluid containing an organic acid and an oxidizing agent to the workpiece. |
