Abstract
A method is described for generating a colour image composed of a plurality of components (Y, U, V) by starting from at least one depth or disparity map (DM1, DM2), wherein a first set of pixels of said at least one depth or disparity map (DM1, DM2) is entered into the luminance component (Y) of said colour image, and wherein a second and a third sets of pixels of said at least one depth or disparity map (DM1, DM2) are entered into the two chrominance components (U, V) of said colour image.
Claims22
A method for generating a color image composed of a plurality of components, starting from at least one depth or disparity map, wherein a first set of pixels of said at least one depth or disparity map is entered into the luminance component of said color image, and wherein a second and a third sets of pixels of said at least one depth or disparity map are entered into the two chrominance components of said color image.
A method for reconstructing at least one depth or disparity map by starting from a color image composed of a plurality of components, wherein a first set of pixels obtained by starting from the luminance component, a second set of pixels obtained by starting from one of the chrominance components, and a third set of pixels obtained by starting from the other chrominance component of said color image are entered into said at least one depth or disparity map.
A method for reconstructing at least one depth or disparity map by starting from a color image composed of a plurality of components, comprising the step of linearly combining values taken from said plurality of components, in contiguous positions, for the purpose of reconstructing values to be copied into said at least one depth or disparity map.
An apparatus for reconstructing at least one depth or disparity map by starting from a color image composed of Y, U, V components, comprising a combiner for entering a first set of pixels obtained by starting from the luminance component (Y), a second set of pixels obtained by starting from one of the chrominance components (U), and a third set of pixels obtained by starting from the other chrominance component (V) of said color image, into said at least one depth or disparity map.
