Sequential block-based disparity map estimation algorithm for stereoscopic image coding

作者：

Highlights：

• A block-based disparity map estimation algorithm for stereo image coding is proposed.

• The optimization algorithm relies on a joint entropy-distortion metric.

• A sub-optimal disparity map is built sequentially using a simplified tree structure.

• Comparisons are done with block-matching algorithms with and without regularization.

• Simulation results show significant gains in terms of rate-distortion.
