Position jitter and undersampling in pattern perception
The present paper addresses whether topographical jitter or undersampling might limit pattern perception in foveal, peripheral and strabismic amblyopic vision. In the first experiment, we measured contrast thresholds for detecting and identifying the orientation (up, down, left, right) of E-like patterns comprised of Gabor samples. We found that detection and identification thresholds were both...
متن کاملLimitations on Position Coding Imposed by Undersampling and Univariance
Position judgements, which are exquisitely precise in the fovea, are markedly degraded in the periphery. In a recent article [Hess & Field (1993) Vision Research, 33, 2663-2670] argue that the poor representation of positional information in peripheral vision is a consequence of uncalibrated spatial disorder of cortical connections rather than due to undersampling of the retinal image. Specific...
متن کاملJitter, Shimmer, and Noise in Pathological Voice Quality Perception
Although jitter, shimmer, and turbulent noise characterize all voice signals, their perceptual importance has not been established psychoacoustically. To determine which of these acoustic attributes is important in listeners’ perceptions of pathologic voices, listeners used a speech synthesizer to adjust levels of jitter, shimmer, and noise so that synthetic voices matched natural pathological ...
متن کاملPattern Generator Model for Jitter-Tolerance Simulation
Version 1, 18 July 2006 This paper discusses the behavioral modeling of a pattern generator including various types of data jitter for jitter tolerance analysis of high-speed serial link receivers during the design phase. The presented model can be used both during the system-level design exploration and the following transistor-level design phases. First, jitter tolerance of clock recovery cir...
متن کاملAnalogical projection in pattern perception
This paper proposes a perceptually motivated method for solving proportional analogy problems involving sequential patterns. Our method is based on an algebraic model of pattern perception that determines the gestalt structure of sequential patterns. The gestalts of sequential patterns are represented as algebraic terms in the model. An analogical relation between sequential patterns appearing ...
