Primary visual cortex (V1) was implicated as an important candidate for the site of perceptual suppression in numerous psychophysical and imaging studies. However, neurophysiological results in awake monkeys provided evidence for competition mainly between neurons in areas beyond V1. In particular, only a moderate percentage of neurons in V1 were found to(More)
In this paper we proposed a novel feature fusion technique in Saliency-Based Visual Attention Model, presented in [Itti, 1998]. There are three conspicuity maps in Saliency-Based Visual Attention Model, which are linearly combined from 12 color maps, 6 intensity maps and 24 orientation maps (42 Feature maps overall) through an Across-scale combination and(More)
Modern microsurgery is a long and complex task requiring the surgeon to handle multiple microscope controls while performing the surgery. Eye tracking provides an additional means of interaction for the surgeon that could be used to alleviate this situation, diminishing surgeon fatigue and surgery time, thus decreasing risks of infection and human error. In(More)
We propose a fast and robust method to estimate the 3D gaze position based on the eye vergence information extracted from eye-tracking data. This method is specially designed for Point-of-Regard (PoR) estimation in non-virtual environments with the aim to make it applicable to the study of human visual attention deployment in natural scenarios. Our approach(More)
