A bio-inspired image coder with temporal scalability [PDF]
, 2011 We present a novel bio-inspired and dynamic coding scheme for static images. Our coder aims at reproducing the main steps of the visual stimulus processing in the mammalian retina taking into account its time behavior. The main novelty of this work is to show how to exploit the time behavior of the retina cells to ensure, in a simple way, scalability ...

Streaming an image through the eye: The retina seen as a dithered scalable image coder [PDF]
arXiv, 2012 We propose the design of an original scalable image coder/decoder that is inspired from the mammalians retina. Our coder accounts for the time-dependent and also nondeterministic behavior of the actual retina. The present work brings two main contributions: As a first step, (i) we design a deterministic image coder mimicking most of the retinal ...

In vivo laser Doppler holography of the human retina [PDF]
Biomed. Opt. Express 9, 4113-4129 (2018), 2018 The eye offers a unique opportunity for non-invasive exploration of cardiovascular diseases. Optical angiography in the retina requires sensitive measurements, which hinders conventional full-field laser Doppler imaging schemes. To overcome this limitation, we used digital holography to perform laser Doppler perfusion imaging of the human retina in ...

Simulation and performance of an artificial retina for 40 MHz track reconstruction [PDF]
, 2014 We present the results of a detailed simulation of the artificial retina pattern-recognition algorithm, designed to reconstruct events with hundreds of charged-particle tracks in pixel and silicon detectors at LHCb with LHC crossing frequency of $40\,\rm MHz$.

Efficient Egocentric Visual Perception Combining Eye-tracking, a Software Retina and Deep Learning [PDF]
arXiv, 2018 We present ongoing work to harness biological approaches to achieving highly efficient egocentric perception by combining the space-variant imaging architecture of the mammalian retina with Deep Learning methods. By pre-processing images collected by means of eye-tracking glasses to control the fixation locations of a software retina model, we ...

The blood–retina barrier in health and disease
The FEBS Journal, 2021 The blood–retina barrier (BRB) is the term used to define the properties of the retinal capillaries and the retinal pigment epithelium (RPE), which separate the systemic circulation from the retina. More specifically, the inner blood–retina barrier (iBRB)

The Role of Early Vitrectomy in the Healing of Retinal Lesions in Progressive Outer Retinal Necrosis
Case Reports in Ophthalmological Medicine, 2022 Purpose. To report on the efficacy of early pars plana vitrectomy (PPV), silicone oil (SO) tamponade, and intravitreal ganciclovir injection in the treatment of a case with progressive outer retinal necrosis (PORN). Case Presentation.

Retinal tissue and microvasculature loss in COVID-19 infection
Scientific Reports, 2023 This cross-sectional study aimed to investigate the hypothesis that permanent capillary damage may underlie the long-term COVID-19 sequela by quantifying the retinal vessel integrity.
