Lateral effects in pattern vision

Pattern Recognition and Machine Vision

Suppose we have a probability density function for some continuous random variable: e.g. a Gaussian or Normal distribution. p(x) = 1 √ 2πσ 2 exp − (x − µ) 2 2σ 2 (1) Usually when we use this function to calculate the probability of getting the value x in the range x to x to x+δ x, we assume that the parameters σ and µ are known or given. To emphasize this point of view, the probability density ...

Effects of acute ethyl alcohol consumption on a psychophysical measure of lateral inhibition in human vision

Acute consumption of ethyl alcohol affects a variety of visual functions. However, there have been few systematic attempts to investigate the neural mechanisms underlying these effects. Here, we employed the Westheimer paradigm to investigate the hypothesis that alcohol reduces lateral inhibition within human "perceptive fields", the psychophysical analogue of physiological receptive fields. We...

Real-time Vision-based Lateral Drift Correction

A major drawback in many robotics projects is the dependance on a specific environment and the otherwise uncertain behavior of the hardware. Simple navigation tasks like driving in a straight line can lead to a strong lateral drift over time in an unknown environment. In this paper we propose a fast and simple solution for the lateral drift problem for vision guided robots by real-time scene an...
