  1. Enhancement of the upconversion luminescence in Y2O3:Er3+ powders by codoping with La3+ ions

  2. Infrared-to-visible upconverted luminescent spectra of Er3+ and La3+ codoped Y2O3 powders are investigated. By introducing La3+ ions, the upconversion green radiation is found to be greatly enhanced when compared with the powders with La3+ absent. Su

  1. Anisotropic edge enhancement in optical scanning holography with spiral phase filtering

  2. Anisotropic edge enhancement is simulated using a spiral phase plate (SPP) in optical scanning holography (OSH). We propose to use a delta function and an SPP as the pupil functions to realize anisotropic edge enhancement. The interference of these t

  1. Variational contrast enhancement guided by global and local contrast measurements for single-image defogging

  2. The visibility of images captured in foggy conditions is impaired severely by a decrease in the contrasts of objects and veiling with a characteristic gray hue, which may limit the performance of visual applications out of doors. Contrast enhancement
