This paper describes a GPU implementation for simultaneous camera ego-motion compensation and lens undistortion. The main idea is to transform the image under an ego-motion constraint so that tracked points in the image, that are assumed to come from the ego-motion, maps as close as possible to their average position in time. The lens undistortion is computed simultaneously. We compare the perf...

Why do people donate blood? Altruism is the common answer. However, altruism is a complex construct and to answer this question requires a systematic analysis of the insights from the biology, economics and psychology of altruism. I term this the mechanism of altruism (MOA) approach and apply it here for understanding blood donor motivation. The answer also has enormous implications for the typ...

There are three prominent solutions to the Darwinian problem of altruism, kin selection, reciprocal altruism, and trait group selection. Only one, reciprocal altruism, most commonly implemented in game theory as a TIT FOR TAT strategy, is not based on the principle of conditional association. On the contrary, TIT FOR TAT implements conditional altruism in the context of unconditionally determin...

The evolution of altruism and reciprocity has been explained mainly from ultimate perspectives. However, in order to understand from a proximate perspective how humans evolved to be such cooperative animals, comparative studies with our evolutionary relatives are essential. Here we review several recent experimental studies on chimpanzees’ altruism and reciprocity. These studies have generated ...

“Group selection” is often cited as an explanation for the survival of altruism. The idea of group selection is a controversial one — much effort has been expended on its justification (and refutation). Relatively little effort has gone into formally testing whether or not it can actually provide a reasonable explanation for altruistic behaviour. This paper concentrates solely on whether or not...

Masses of experiments have shown individual preference for fairness which seems irrational. The reason behind it remains a focus for research. The effect of spite (individuals are only concerned with their own relative standing) on the evolution of fairness has attracted increasing attention from experiments, but only has been implicitly studied in one evolutionary model. The model did not invo...

Previous research on political orientations, which can be understood as one’s leftversus right-wing attitude, has shown that some personality factors yield explanatory power. In the current work, we consider the role of altruism – a personality construct which does not exclusively map onto one of the broad personality dimensions typically studied. Altruism was predicted to relate to left-wing a...
