Then take the area under the ROC curve, a quantity usually called Az, as the measure of detection ability. Az can vary from 0 to 1. 5 indicate no detection ability. 5, the higher the value the greater the detection ability, with a value of 1 indicating perfect detection ability. There are two basic techniques for measuring empirically several points on the ROC. A key idea is that the different points on a single ROC curve correspond to different response criteria. By inducing the observer to adopt different response criteria, one can measure different points on the ROC curve.

The observer wishes to make inferences about some properties designated S of the visual scene. This S might be the presence or absence of a pedestrian on the road ahead; the three-dimensional shape of the car just ahead; the speed at which the observer is driving down the road; the angle at which the road bends at the next curve; the colour of the signal light at the next intersection. In each case we will simply refer to these properties of the scene by the symbol S. The observer wishes to make inferences about S from the information I.

The result is genetic drift; more or less random drifting of the genetic constitution that is irrelevant to reproductive success. The implications of this account for the evolution of the visual system are intriguing. The only selection pressures in the evolution of the visual system arise from its effects on reproductive success. e. behaviours that are more likely to lead to reproductive success, are more likely to have offspring. 44 2 How Vision Constructs Reality These offspring are more likely to inherit visual systems that, like those of their parents, guide adaptive behaviours.
