Application of morphology filters to compensation of lateral illumination inhomogeneities in confocal microscopy images
Michálek, Jan ; Čapek, Martin ; Mao, X. W. ; Kubínová, Lucie
Due to multiple distortion effects, confocal laser scanning microscopy (CLSM) images of even homogeneous specimen regions suffer from irregular brightness variations. In this paper, a fast correction method based on estimating a spatially variable illumination gain, and multiplying acquired CLSM images by the inverse of the estimated gain, is presented. The method does not require any special calibration (reference) images since the gain estimate is extracted from the CLSM image being corrected itself. The proposed approach exploits two types of morphological filters: the median filter and a morphological operator called the upper Lipschitz cover
Fitting geometrical models to 3D confocal microscopy images using graph cuts iteratively
Janáček, Jiří
A new iterative method for fitting triangulated surfaces and geometric graphs to surfaces and fibre-like structures is based on the calculation of the minimal graph cut in every iteration. The method was used for improvement of the geometric model of muscle fibres surfaces and capillaries in skeletal muscle from 3D confocal image
