Contrast discrimination in noise.
Even the highest contrast sensitivities that humans can achieve for the detection of targets on uniform fields fall far short of ideal values. Recent theoretical formulations have attributed departures from ideal performance to two factors--the existence of internal noise within the observer and suboptimal stimulus information sampling by the observer. It has been postulated that the contributi...
متن کاملPulse and steady-pedestal contrast discrimination: effect of spatial parameters
The goal of this study was to establish the spatial summation properties associated with inferred PC- and MC-pathway mediated psychophysical contrast discrimination. Previous work has established two paradigms that reveal characteristic signatures of these pathways. In the pulse paradigm, a four-square array was pulsed briefly, on a constant background. In the steady-pedestal paradigm, the stim...
متن کاملStereoscopic depth discrimination with contrast windowed stimuli
Depth discrimination with a shifted contrast window was compared to that with a fixed contrast window. Stereoscopic performance with the fixed window was limited to small disparities and varied with spatial frequency. Performance with the shifted window extended to larger disparities and was more similar for low and high spatial frequencies. The results depended upon window shape, indicating th...
متن کاملThe effects of contrast on perceived depth and depth discrimination
The contrast dependence of perceived depth was quantified through a series of depth matching experiments. Perceived depth was found to be a power law function of contrast. In addition, subjects exhibited a large uncrossed depth bias indicating that low contrast test patterns appeared much farther away than high contrast patterns of equal disparity. For disparities in the range of +/- 4.0 arc mi...
متن کاملFirst-order motion from contrast modulated noise?
The class of microbalanced motion stimuli is thought to contain no systematic directional biases in motion energy. The fact that we can see motion in such stimuli implies that models of human motion perception based on Fourier decomposition need to be revised. The validity of one widely studied class of microbalanced stimuli, contrast modulated noise, has recently been questioned. It has been p...
