In this paper a methodology for automatic extraction of road segments from images with different resolutions (low, middle and high resolution) is presented. It is based on a generalized concept of lines in digital images, by which lines can be described by the centerlines of two parallel edges. In the specific case of low resolution images, where roads are manifested as entities of 1 or 2 pixels wide, the proposed methodology combines an automatic image enhancement operation with the following strategies: automatic selection of the hysteresis thresholds and the Gaussian scale factor; line length thresholding; and polygonization. In medium and high resolution images roads manifest as narrow and elongated ribbons and, consequently, the extraction goal becomes the road centerlines. In this case, it is not necessary to apply the previous enhancement step used to enhance roads in low resolution images. The results obtained in the experimental evaluation satisfied all criteria established for the efficient extraction of road segments from different resolution images, providing satisfactory results in a completely automatic way.

This article analyzes the pedagogical coordination work in public schools of the state of São Paulo within a context of educational reforms occurred between 1996 and 2010. The paper analyzes the main resolutions published by the Secretariate of Education regarding the functions performed by coordinating teachers, and discusses data obtained from empirical research conducted with three schools in inner cities of the state of São Paulo, specifically in the final years of elementary school and high-school. The analysis has enabled us to identify the implications of educational reforms on the functions of coordinating teachers. In addition, we have identified and interpreted the ways in which subjects are (re)adjusted in school management and organization.
