Device and method for creating a saliency map of an image
Résumé
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.
