Abstract
In this paper, we propose an automatic method adapted to the detection of thermal fronts by the analysis of images whatever the geographical zones. This method is composed of two stages. Firstly, the image is locally thresholded in order to localize the candidate points of the fronts; secondly, a contour following is carried out in accordance with the priority criterion associated with each candidate extension point. The method developed has been tested on images obtained from the Advanced Very High Resolution Radiometer aboard the NOAA-11 satellite. The results obtained are similar to those issued from manual detection.
