ABSTRACT:
The invention concerns a device and a method for creating a saliency map of an image. It comprises the steps of:Projection of said image according to the luminance component and if said image is a color image, according to the luminance component and according to the chrominance components,Perceptual sub-bands decomposition of said components according to the visibility threshold of a human eye,Extraction of the salient elements of the sub-bands related to the luminance component,Contour enhancement of said salient elements in each sub-band related to the luminance component,Calculation of a saliency map from the contour enhancement, for each sub-band related to the luminance component.Creation of the saliency map as a function of the saliency maps obtained for each sub-band.
