Single-sensor digital cameras capture image by covering the sensor surface with a color filter array(CFA) such that each sensor pixel only samples one of three primary color values  three color is R(red)  G(green) and B(blue). To render a full-color image  need an interpolation process commonly referred to as CFA demosaicking  is required to estimate the other two contributions for producing a full-color image. But  the noise in imaging sensors not only corrupts the color filter array  at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images  adopt a sort of viable and effective interpolation algorithm based on gradient  at the time of removing the noise  reserve image border and detail information clearly. 2012 IEEE.  

Tungsten tellurite glasses doped with Er3+  Tm3+  Pr3+  and Ho3+ ions were prepared by melt quenching. The glass matrix was the same for all types of glasses and had a high sodium content in order to allow the fabrication of waveguides using an ion-exchange technique. The absorption spectra of the glasses were measured and the Judd-Ofelt parameters q were obtained from the experimental oscillator strengths of the f &rarr f transitions. Er3+ doped glasses showed a very high quantum efficiency when comparing the calculated radiative decay time with the measured lifetime of the 4I 13/2 metastable level. Ag+ Na+ ion-exchanged planar waveguides were successfully obtained in all types of glasses and characterized by the prism coupling technique. It turned out that the diffusion constant values are very similar for glasses containing different rare-earth ions with the same concentration  while  at least for the Er 3+ doped ones  the diffusion constant changes with the ions concentration. 2004 Elsevier B.V.

The  J/Ψ  hadronic  decays  involving  2(π+π-)π°and  2(K+K-)  final  states  are  investigated  by  using  the  sample  of  2.5  *  10~6  J/Ψ's  which  were  obtained  from  the  BES  detector  at  BEPC  in  the  first  half  of  1990.  Some  signals  such  as  ω(782)  φ(1020)  f2(1270)  f2'(1525)  θ/f2(1720)  b1(1235)  and  a2(1320)  have  been  found  and  measured  the  mass  width  and  branching  fraction  of  reasonance  states.  The  results  are  agreement  with  the  world  average  values.  The  ratio  of  Br(J/Ψ  →  ω  f2(1270))/Br(J/Ψ→ρ°a2°)  shows  that  doubly  OZI  violating  effects  play  a  role  in  the  J/Ψ  →  ω  f2(1270)  f2(1270)  →  π+π-  are  given  in  the  first  time:  x  =  0.99  ±  0.29  Y  =  -0.24  ±  0.17  Z1  =  0.90  ±  0.57  Z2  =  0.56  ±  0.22.
