Purpose. To evaluate visual performance for near, intermediate, and distant vision; complaints of photic phenomena, and patient satisfaction with the new diffractive multifocal IOL used in eyes which underwent phacoemulsification. Methods. Two thousand and five hundred consecutive eyes undergoing Tecnis ZM900 multifocal IOL implantation were included in this retrospective analysis. The minimum ...

The computation of structure and motion from an image sequence is a fundamental problem in vision. A fully automatic approach requires not only an understanding of geometry, on which a wide range of work has been carried out in the past, but also the ability to deal with incorrect data (such as mismatched features) which will inevitably arise in a real system. It is often assumed that a standar...

Sunlight conditions can reduce drivers’ visibility, which is a safety concern on road networks. This research introduces method to study sun glare incidence in environments. Sun areas during daylight hours are automatically detected from mobile laser scanning (MLS) and aerial (ALS) point clouds. The comprises the following steps. First, Sun’s position (solar altitude azimuth) referring location...

We report observations of three SDSS z > 6 QSOs at 250 GHz (1.2 mm) using the 117-channel MaxPlanck Millimeter Bolometer (MAMBO-2) array at the IRAM 30-meter telescope. J1148+5251 (z = 6.41) and J1048+4637 (z = 6.23) were detected with 250 GHz flux densities of 5.0±0.6mJy and 3.0±0.4 mJy, respectively. J1630+4012 (z = 6.05) was not detected with a 3σ upper limit of 1.8 mJy. Upper flux density l...
