Registration of retinal images from Public Health by minimising an error between vessels using an affine model with radial distortions [PDF]
, 2019 In order to estimate a registration model of eye fundus images made of an affinity and two radial distortions, we introduce an estimation criterion based on an error between the vessels.

Acta Ophthalmologica, Volume 104, Issue 2, Page 201-211, March 2026.Abstract Background Imaging of the retina is accompanied by distortions so that positions in fundus photographs cannot be linearly translated to positions in the retinal fundus. The purpose of this study was to describe an algorithm and evaluate its reproducibility in identifying points on the retina from their representation on serial fundus ...

Journal of Diabetes Investigation, Volume 17, Issue 3, Page 483-491, March 2026.Under physiological conditions, deformable erythrocytes pass smoothly through the capillary network, maintaining retinal capillary perfusion (A). In pathological conditions, reduced erythrocyte deformability causes irregular passage and stagnation within capillaries, resulting in localized blood flow stasis and microvascular congestion, leading to ...
