1. 1. Deconvolution algorithms of 2D Transmission Electron Microscopy images

   University essay from KTH/Optimeringslära och systemteori

   Author : Ting Meng; Yating Yu; [2012]
   Keywords : Deconvolution; Image restoration; Wiener lter; Wiener deconvolution;

   Abstract : The purpose of this thesis is to develop a mathematical approach and associated software implementation for deconvolution of two-dimensional Transmission Electron Microscope (TEM) images. The focus is on TEM images of weakly scattering amorphous biological specimens that mainly produce phase contrast. READ MORE

3. 2. 3D imaging using time-correlated single photon counting

   University essay from Signaler och System

   Author : Thomas Neimert-Andersson; [2010]
   Keywords : Laser radar; LADAR; time-of-flight; signal processing; non-linear least squares; esprit; time-correlated single photon counting; three-dimensional imaging; range profiling; deconvolution; wiener filter; richardson-lucy algorithm; image processing; watershed;

   Abstract : This project investigates a laser radar system. The system is based on the principles of time-correlated single photon counting, and by measuring the times-of-flight of reflected photons it can find range profiles and perform three-dimensional imaging of scenes. READ MORE

4. 3. On the Influence of Sensor Dynamics in Estimation of Reactor Noise Signals

   University essay from KTH/Reglerteknik

   Author : Elisabeth Lindell; [2004]
   Keywords : ;

   Abstract : The qualities of measured signals are always affected by the measurement systems and noise. If these effects can be modelled, the original signals can be restored. Two methods for estimation of signals are studied in this work, the causal Wiener deconvolution filter and the Kalman filter. READ MORE
