For the problems that the traditional local SAD algorithm is affected by the central pixels largely and noise easily, this paper puts forward a new Rank-transform stereovision matching algorithm based on window weighted function. Firstly, the traditional nonparametric Rank transformation is used for left and right gray images to suppress the noise; meanwhile, the weighted window function is add...

Although many animal species can represent numerical values, little is known about how salient number is relative to other object properties for nonhuman animals. In one hypothesis, researchers propose that animals represent number only as a last resort, when no other properties differentiate stimuli. An alternative hypothesis is that animals automatically, spontaneously, and routinely represen...

Intelligent visual surveillance by multiple cameras has becoming more and more important in recent years. A novel and effective method to match objects between multiple cameras is proposed in this work, based on the proposed wavelet salient features. Firstly, the background and foreground is separated based on Gaussian Mixture Model (GMM). To achieve a reliable matching objects between cameras,...

The relationship between attentional control and episodic representation was investigated in six experiments that employed a variant of the classic attentional blink paradigm. We introduced a task-irrelevant (unpredictive) color match between the first and second target stimulus in a three-stream rapid serial visual presentation task. When this match was present, the first target reliably elici...

The goal of the present work is to reduce the number of the training samples used in our color prediction model based on CIEXYZ using an Effective Coverage Map while keeping satisfying prediction. A general approach is proposed in this paper to choose the best reference combination for the training samples. The approach is based on the dot gain behavior of each primary ink, which is characteriz...

Several tests of visual function were applied to an abstaining user (10 years or more) group and a nonuser group carefully preselected to be free of clinical signs of eye disease. The groups were matched on several criteria. The results show that all findings from both groups are within established limits of normalcy. Small differences and trends were found between the groups. These would have ...

Introduction: Human eye colour as a physical trait is based on the developmental biology and genetic determinants of the structure known as the iris, which is part of the uveal tract of the eye. Prediction of human visible characteristics (EVCs) by genotyping informative SNPs in DNA as biological witness opens up a new avenue in the forensic genetic. Variation of iris color rely on the amounts...
