The invention discloses a three-dimensional video
depth map coding method based on just distinguishable
parallax error
estimation. The method comprises the following steps: (1), inputting a frame of three-dimensional video
depth map and a corresponding texture image; (2), synthesizing the texture image of a virtual view point; (3), calculating the just distinguishable error graph of the texture image of the virtual view point; (4), calculating the scope of a just distinguishable
parallax error of the three-dimensional video
depth map; (5), performing intraframe and interframe prediction on the three-dimensional video depth map, and selecting a prediction mode, which is provided with minimum
prediction residual error energy, of the three-dimensional video depth map; (6), performing
prediction residual error adjusting on the three-dimensional video depth map, and obtaining a
prediction residual error block, which has a minimum variance, of the three-dimensional video depth map; and (7), encoding the three-dimensional video depth map of a current frame. The method provided by the invention, can greatly reduce the
code rate of
depth map coding under the condition that the invariability of the PSNR of a virtual synthesis
video image is ensured and can also substantially improve the
subjective quality of a virtual synthesis viewpoint at the same time.
