Understanding How Young Adults Perceive Blurred Image Quality and Creating a Model Predicting Their Quality Ratings

Starting soon · Not applicable

Conditions studied: Healthy Young Adults

In brief

This clinical study wants to understand how blurred images look to young adults. The main question is: How do different kinds of images and different kinds of blur change the way people think those images look? Participants will get an eye exam, then look at several blurred images and rate how good or bad each one looks on a quality scale from 1 (very bad) to 10 (very good).
