On Picture (2+1)-tqfts

The goal of the paper is an exposition of the simplest (2 + 1)TQFTs in a sense following a pictorial approach. In the end, we fell short on details in the later sections where new results are stated and proofs are outlined. Comments are welcome and should be sent to the 4th author.

Picture Perception and the Two Visual Subsystems

I aim to give a new account of picture perception: of the way our visual system functions when we see something in a picture. My argument relies on the functional distinction between the ventral and dorsal visual subsystems. I propose that it is constitutive of picture perception that our ventral subsystem attributes properties to the scene, whereas our dorsal subsystem attributes properties to...

Reliability of Objective Picture Quality Measures

This paper investigates a set of objective picture quality measures for application in still image compression systems and emphasizes the correlation of these measures with subjective picture quality measures. Picture quality is measured using nine different objective picture quality measures and subjectively using Mean Opinion Score (MOS ) as measure of perceived picture quality. The correlati...

Perceptual-Based Objective Picture Quality Measurements

Understanding QMM Objective Picture Quality Measurements

Digital television broadcast systems based on MPEG can compress video information from hundreds of megabits to less than 5 Mbps with very little user perceived picture quality degradation. This is the case as long as everything goes well. However, given the complexity of today’s digital television broadcast chain, problems can give rise to poor picture quality being delivered to the end user. T...
