Stratego is a game of imperfect information, where observations of the opponent’s behaviour are crucial for determining the best move. This article describes how one can model the opponent in the game of Stratego, using a Bayesian approach. By observing the moves of the opponent, a probability distribution can be derived to help determine the identity of unknown pieces of the opponent. Experime...

This work concentrates on the problem of watermarking embedding and optimum detection in color images through the use of spread spectrum techniques, both in space (Direct Sequence Spread Spectrum or DSSS) and frequency (Frequency Hopping). It is applied to RGB and opponent color component representations. Perceptive information is considered in both color systems. Some tests are performed in or...

In this paper we present a new opponent color system which imitates some of the known color processing neural cells established by electrophysiological recordings. We describe the benefits of this system to image processing tasks. The opponent color model is embedded in an active vision system to improve the systems fixation and recognition capabilities. This is done by removing illumination ef...

A symmetrical model of color vision, the decoding model as a new version of zone model, was introduced. The model adopts new continuous-valued logic and works in a way very similar to the way a 3-8 decoder in a numerical circuit works. By the decoding model, Young and Helmholtz's tri-pigment theory and Hering's opponent theory are unified more naturally; opponent process, color evolution, and c...

In regard to colored lights, an opponent cell will indeed increase its firing to luminance increments (as well as to equiluminant color increments) but this does not at all imply confounding; rathe, r, in both cases, the cell will signal more color. Alternatively stated, when one increases the luminance (or radiance, or energy, etc.) of a colored light, any theory must predict that its chromati...

sensitivity curve for 1° 200 ms. flashes on a white background may be a rather precise indicator of the functioning of the opponent-color system. Thus, although J. T. believed that his right eye was normal, the corresponding spectral sensitivity curve (continuous curve, Fig. 3) lies near the limit of the normal range, indicating that his right eye may have been partially affected by a similar d...

Persuasive negotiation involves negotiating using rhetorical arguments (such as threats, rewards, and appeals), which act as persuasive elements that aim to force or convince an opponent to accept a given proposal. In the case of rewards, these have a positive nature as they use the argument that something positive will happen to the opponent if he accepts to do the requirement sent by the prop...

Many of the parvocellular pathway (PC) cells in primates show red-green spectral selectivity (cone opponency), but PC ganglion cells in the retina show no anatomical signs of cone selectivity. Here we asked whether responses of PC cells are compatible with "random wiring" of cone inputs. We measured long-wavelength-sensitive (L) and medium-wavelength-sensitive (M) cone inputs to PC receptive fi...

This thesis focuses on decision making in partially observable card games and, in particular, poker games. An attempt is made to outline both the game theoretic, as an agent-centric approach to such games, analyzing differences and similarities, as well as strong and weaker points and finally proposing a view to make a tradeoff between these. The game theoretic approach for this type of games w...

We investigate the relevance of conditional reasoning and belief formation for the occurrence of the winner’s curse with the help of two experimental manipulations. First, we compare results from a very simple common-value auction game with results from a transformed version of this game that does not require any conditioning on future events. In human opponent settings, we observe significant ...
