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 کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
