Increments and decrements in color constancy.
The present study examines whether increment-decrement asymmetries reported in a number of recent center-surround situations occur in more complex images as well. Subjects saw the CRT simulation of a whole uniformly illuminated array of foreground surfaces presented against a large background surface and, for a number of different viewing contexts, made achromatic settings over a wide range of ...
متن کاملThreshold Counters with Increments and Decrements
A threshold counter is a shared data structure that assumes integer values It provides two operations Increment changes the current counter value from v to v while Read returns the value bv wc where v is the current counter value and w is a xed constant Thus the Read operation returns the approximate value of the counter to within the constant w Threshold counters have many potential uses inclu...
متن کاملThreshold Counters with Increments a Decrements
A threshold counter is a shared data structure that assumes integer v ues. It provides two operations: Increment changes the current counter val from v to v+1, while Read returns the value bv=wc, where v is the curre counter value and w is a fixed constant. Thus, the Read operation retur the “approximate” value of the counter to within the constant w. Thresho counters have many potential uses, ...
متن کاملNoise masking of S-cone increments and decrements.
S-cone increment and decrement detection thresholds were measured in the presence of bipolar, dynamic noise masks. Noise chromaticities were the L-, M-, and S-cone directions, as well as L-M, L+M, and achromatic (L+M+S) directions. Noise contrast power was varied to measure threshold Energy versus Noise (EvN) functions. S+ and S- thresholds were similarly, and weakly, raised by achromatic noise...
متن کاملBrightness induction: unequal spatial integration with increments and decrements.
Modern theories of brightness induction include an influence from regions that do not share a border with the target. This study tested whether the spatial range of neural integration is the same with incremental versus decremental contrast edges in relatively remote parts of the background. Using an asymmetric matching task, observers set the brightness of a comparison ring, within its own uni...
