TL;DR: It is shown that for downsampled images the signal power in the phase correlation is not concentrated in a single peak, but rather in several coherent peaks mostly adjacent to each other.

TL;DR: The least-squares Gaussian approximations of the diffraction-limited 2D-3D paraxial-nonparaxial point-spread functions (PSFs) of the wide field fluorescence microscope (WFFM), the laser scanning confocal microscope (LSCM), and the disk scanning conf focal microscope (DSCM) are studied.

TL;DR: This work proposes to combine the Richardson–Lucy algorithm with a regularization constraint based on Total Variation, which suppresses unstable oscillations while preserving object edges and shows that this constraint improves the deconvolution results as compared with the unregularized Richardson– Lucy algorithm, both visually and quantitatively.

TL;DR: In this paper, the authors present a comparative study of different techniques for segmentation of images, including filtrage du bruit, extraction of contours, and extraction of regions.

TL;DR: A supervised classification model based on a variational approach to find an optimal partition composed of homogeneous classes with regular interfaces and shows how these forces can be defined through the minimization of a unique fonctional.
