Depth maps play an important role in 3DTV applications for rendering stereo views. Most existing automatic algorithms cannot generate an acceptable quality of depth maps from a mono-channel video sequence. Proposed is a key-frame depth propagation algorithm, combining trilateral filtering to produce high-quality depth sequences. Experiment results show that the algorithm outperforms a well-known prior work in terms of depth PSNR by up to 3.5 dB.
