Abstract
Methods, apparatus, systems and articles of manufacture for texture based immersive video coding are disclosed. An example apparatus includes a correspondence labeler to (i) identify first unique pixels and first corresponding pixels included in a plurality of pixels of a first view and (ii) identify second unique pixels and second corresponding pixels included in a plurality of pixels of a second view; a correspondence patch packer to (i) compare adjacent pixels in the first view and (ii) identify a first patch of unique pixels and a second patch of corresponding pixels based on the comparison of the adjacent pixels and the correspondence relationships, the second patch of corresponding pixels tagged with a correspondence list identifying corresponding patches in the second view; and an atlas generator to generate at least one atlas to include in encoded video data, the encoded video data not including depth maps.
