Adaptive Trilateral Filter for In-Loop Filtering
Computer Science & Information Technology ( CS & IT ), 2014 High Efficiency Video Coding (HEVC) has achieved significant coding efficiency improvement beyond existing video coding standard by employing several new coding tools. Deblocking Filter, Sample Adaptive Offset (SAO) and Adaptive Loop Filter (ALF) for in-loop filtering are currently introduced for the HEVC standard.

Optically controlled Sagnac loop comb filter
Optics Express, 2004 We propose a new type of dynamically tunable birefringence comb filter based on a semiconductor optical amplifier Sagnac loop interferometer. By optically modulating the birefringence of the amplifier, we demonstrate a tuning of the output wavelengths. The shift of wavelength increases monotonically with the power of the control light until saturation ...

Discovery of spatial periodicities in a coronal loop using automated edge-tracking algorithms [PDF]
, 2008 A new method for automated coronal loop tracking, in both spatial and temporal domains, is presented. Applying this technique to TRACE data, obtained using the 171 Å filter on 1998 July 14, we detect a coronal loop undergoing a 270 s kink-mode ...

Design of loop filter in phase-locked loops
Electronics Letters, 1999 An exact method for designing loop filters in third-order PLLs is presented. The method is simple and results in a PLL with superior loop dynamics and improved output jitter while maintaining the same loop bandwidth compared to that of a PLL designed using the conventional approach. The method is readily applicable to higher order PLLs.
