Per una educació intercultural

L'escola tradicional s'ha vist impotent quan s'ha reconegut el dret que tenen tots els alumnes a rebre atenció educativa en els centres ordinaris, independentment de les seves característiques individuals. Si, per una banda, la realitat escolar és -i ha estat sempre- heterogknia i desigual, per l'altra, tots els alumnes participen d'un mateix sistema educatiu que es proposa el ple desenvolupament de la seva personalitat, l'adquisició d'hibits intel.lectuals, de tkcniques de treball i de coneixements en tots els imbits del saber, la capacitació per a l'exercici d'activitats professionals, la preparació per participar activament en la vida social i cultural ... tal i com ha quedat escrit en l'article 1 de la LOGSEL

Proposal of a parallel architecture for a motion detection algorithm

This paper proposes a parallel architecture for estimation of the motion of an underwater robot. It is well known that image processing requires a huge amount of computation, mainly at low-level processing where the algorithms are dealing with a great number of data. In a motion estimation algorithm, correspondences between two images have to be solved at the low level. In the underwater imaging, normalised correlation can be a solution in the presence of non-uniform illumination. Due to its regular processing scheme, parallel implementation of the correspondence problem can be an adequate approach to reduce the computation time. Taking into consideration the complexity of the normalised correlation criteria, a new approach using parallel organisation of every processor from the architecture is proposed

A new approach to real time traffic sign recognition based on colour information

The automatic interpretation of conventional traffic signs is very complex and time consuming. The paper concerns an automatic warning system for driving assistance. It does not interpret the standard traffic signs on the roadside; the proposal is to incorporate into the existing signs another type of traffic sign whose information will be more easily interpreted by a processor. The type of information to be added is profuse and therefore the most important object is the robustness of the system. The basic proposal of this new philosophy is that the co-pilot system for automatic warning and driving assistance can interpret with greater ease the information contained in the new sign, whilst the human driver only has to interpret the "classic" sign. One of the codings that has been tested with good results and which seems to us easy to implement is that which has a rectangular shape and 4 vertical bars of different colours. The size of these signs is equivalent to the size of the conventional signs (approximately 0.4 m2). The colour information from the sign can be easily interpreted by the proposed processor and the interpretation is much easier and quicker than the information shown by the pictographs of the classic signs
