On a discretization of confocal quadrics. II. A geometric approach to general parametrizations
, 2017 We propose a discretization of classical confocal coordinates. It is based on a novel characterization thereof as factorizable orthogonal coordinate systems. Our geometric discretization leads to factorizable discrete nets with a novel discrete analog of

Optics Express, 2012 We demonstrate experimentally a scanning confocal microscopy technique based on digital holography. The method relies on digital holographic recording of the scanned spot. The data collected in this way contains all the necessary information to digitally produce three-dimensional images. Several methods to treat the data are presented.

Self-Supervised Joint Learning for pCLE Image Denoising
SensorsProbe-based confocal laser endoscopy (pCLE) has emerged as a powerful tool for disease diagnosis, yet it faces challenges such as the formation of hexagonal patterns in images due to the inherent characteristics of fiber bundles.

Indian Journal of Dermatology, Venereology and Leprology, 2006 The confocal laser microscope is a novel and interesting noninvasive tool for imaging skin lesions and subsurface skin lesions that are not visible to the naked eye or even by dermoscopy. Skin can be imaged in vivo or freshly biopsied (in vitro) skin specimens can be visualized immediately without the processing that is required for routine ...

Incircular nets and confocal conics
, 2017 We consider congruences of straight lines in a plane with the combinatorics of the square grid, with all elementary quadrilaterals possessing an incircle. It is shown that all the vertices of such nets (we call them incircular or IC-nets) lie on confocal
