There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Understanding Perceived Quality through Visual Representations
Committee:
Dr. AlRegib, Advisor
Dr. McClellan, Chair
Dr. Anderson
Abstract: The objective of the proposed research is to investigate the role of visual system characteristics, color perception mechanisms and spatial pooling strategies in perceptual image quality assessment. More specifically, we focus on the contrast sensitivity mechanisms in the retinal ganglion cells and the suppression mechanisms in cortical neurons to partially model the visual system. Furthermore, we utilize color difference equations and color descriptors to mimic color perception. We also analyze spatial pooling strategies to investigate the significance of pooling and utilize data-driven approaches to estimate the perceived quality of images.
