1. Automatic detection method of detecting at least one area called a layout area in a source image, comprising at least one layout, wherein said method comprises: generating a saliency map of said image source using a visual attention model, said saliency map associating with each pixel of the source image a salience point having a salience value, and determining, from said saliency map, said at least one layout area in the source image, wherein said determining comprises: searching for within at least one predefined area of the saliency map known as the search area, two points having the same or nearly the same salience value as the maximum salience value of said saliency map and which are distant by at least p points, and defining, for each of the two points of maximum salience, a maximum salience area, bounding the maximum salience point, and defining a window for each search area comprising two maximum salience areas, called a bounding window, bounding said two maximum salience areas, said bounding window thus defined in the saliency map corresponding to a layout area in the source image.
