Automated Identification of Diabetic Retinopathy Using Deep Learning.

PURPOSE: Diabetic retinopathy (DR) is one of the leading causes of preventable blindness globally. Performing retinal screening examinations on all diabetic patients is an unmet need, and there are many undiagnosed and untreated cases of DR. The objective of this study was to develop robust diagnostic technology to automate DR screening. Referral of eyes with DR to an ophthalmologist for further e...

Performance evaluation of 3D vision-based semi-autonomous control method for assistive robotic manipulator.

We developed a 3D vision-based semi-autonomous control interface for assistive robotic manipulators. It was implemented based on one of the most popular commercially available assistive robotic manipulator combined with a low-cost depth-sensing camera mounted on the robot base. To perform a manipulation task with the 3D vision-based semi-autonomous control interface, a user starts operating with a...

Extending the Stabilized Supralinear Network model for binocular image processing.

The visual cortex is both extensive and intricate. Computational models are needed to clarify the relationships between its local mechanisms and high-...

Decision Support System for Detection of Papilledema through Fundus Retinal Images.

A condition in which the optic nerve inside the eye is swelled due to increased intracranial pressure is known as papilledema. The abnormalities due t...

Grain classifier with computer vision using adaptive neuro-fuzzy inference system.
