1. A computer implemented method for transmitting three-dimensional (3D) imagery, comprising the steps of:
- extracting a depth map and color data from at least one 3D image;
reducing bandwidth of the depth map to produce reduced bandwidth depth map;
inserting the reduced bandwidth depth map into the color data to produce a reduced bandwidth 3D image; and
transmitting the reduced bandwidth 3D image into a transmission channel for delivery to a display.

Abstract
A digital image processing system takes color plus Z channel data as input, preprocesses, decimates, and codes the Z channel in-band as digital watermark data embedded within the color data prior to encoding and transmission. A second digital image processing system receives, decodes, and extracts the decimated Z channel data before applying statistical regularization to restore a full-resolution Z channel prior to depth-image-based rendering.
