Abstract:
An apparatus is arranged to generate a triangle mesh for a three dimensional image. The apparatus includes a depth map source ( 101 ) which provides a depth map and a tree generator ( 105 ) generates a k-D tree from the depth map. The k-D tree representing a hierarchical arrangement of regions of the depth map satisfying a requirement that a depth variation measure for undivided regions is below a threshold. A triangle mesh generator ( 107 ) positions an internal vertex within each region of the k-D tree. The triangle mesh is then generated by forming sides of triangles of the triangle mesh as lines between internal vertices of neighboring regions. The approach may generate an improved triangle mesh that is suitable for many 3D video processing algorithms.

Claim (Index 14):
An apparatus for generating a triangle mesh, the apparatus comprising:\n a receiver circuit arranged to receive a video signal, the video signal comprising image data, wherein the image data comprises a representation of a three dimensional image and a k-D tree for a depth map of the three dimensional image, wherein the depth map comprises regions, wherein the k-D tree represents a hierarchical arrangement of the regions, wherein the hierarchical arrangement of the regions satisfies a requirement that a depth variation measure for regions is below a threshold; and a triangle mesh generator circuit arranged to position an internal vertex within each of the regions of the k-D tree, wherein the triangle mesh generator circuit is arranged to generate the tringle mesh by forming sides of triangles of the triangle mesh as lines between internal vertices of neighboring regions.
