device and method for generating a mapping herausstechender features in an image

摘要

The invention concerns a device and a method for creating a saliency map of an image. It comprises the steps of :Projection (E1) of said image according to the luminance (A) component and if said image is a color image, according to the luminance (A) component and according to the chrominance components (Cr1, Cr2),Perceptual sub-bands decomposition (E3, T2, T'2, T"2) of said components (A, Cr1, Cr2) according to the visibility threshold of a human eye,Extraction (E7) of the salient elements of the sub-bands related to the luminance (A) component,Contour enhancement (E8, T7) of said salient elements in each sub-band related to the luminance (A) component,Calculation (T7) of a saliency map from the contour enhancement, for each sub-band related to the luminance (A) component.Creation (T8) of the saliency map as a function of the saliency maps obtained for each sub-band.
