Fundamentos pedagógicos de la programación de un centro docente.

Se analiza la necesidad de crear centros docentes integrados, las ventajas didácticas de un curso común a todos los alumnos, independientemente de si han obtenido la graduación o la certificación escolar, dirigido a su orientación escolar y profesional. Se expone, a modo de ejemplo, la programación de los espacios docentes de un centro integrado de 480 alumnos.

Extração de vias combinando métodos de detecção de regiões e linhas em imagens de intensidade de pulso laser

This paper aims at extracting street centerlines from previously isolated street regions by using the image of laser scanning intensity. In this image, streets are easily identified, since they manifest as dark, elongate ribbons contrasting with background objects. The intensity image is segmented by using the region growing technique, which generates regions representing the streets. From these regions, the street centerlines are extracted in two manners. The first one is through the Steger lines detection method combined with a line length thresholding by which lines being shorter than a minimum length are removed. The other manner is by combining the skeletonization method of regions based on the Medial Axis Transform and with a pruning process to eliminate as much as possible the ramifications. Experiments showed that the Steger-based method provided results better than the method based on skeletonization.
