The dynamic expectation maximization algorithm (dEM) has been developed to determine the kinetic information of various metabolic processes from SPECT projection data acquired with a single slow camera rotation. Depth-dependent detector response compensation (DRC) has been tested as a means to improve the accuracy of these reconstructions. As well, by limiting the number of temporal frames in a...

This paper presents a new incremental algorithm for directly estimating depth maps from image sequences, which is based on the modiied motion constraint equation. In order to overcome the inherent problem of the gradient-based methods which are sensitive to noise and guarantee a moderate cost, we make a scalar Kalman ltering approach with some compensation considering discontinuity and occlusio...

Telecentric architecture is proposed for circumventing, by the pure-optical method, the residual parabolic phase distortion inherent to standard configuration of digital holographic microscopy. This optical circumvention produces several important advantages. One is that there is no need for computer compensation of the parabolic phase during the phase map recovering procedure. The other is tha...

We theoretically evaluate the prediction efficiency of the overlapped block motion compensation (OBMC) compared with the conventional non-overlapped approach. Based on the one-dimensional signal model characterized by the AR(1) process and first-order polynomial motion, a condition under which the performance of the OBMC is better, and an optimum window function are derived. From the results, w...

We motivate and analyse a reaction-advection-diffusion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent diffusion in a water column of given depth. Furthermore, it might be sinkin...
