Embodiment Construction
[0037] One implementation of the invention is as follows.
[0038] The present invention takes encoding reference software JM18.0 and virtual visual synthesis reference software VSRS3.5 as experimental platforms, and the video sequences in the test are as follows: figure 1 As shown, the table shows the parameters of Akko&Kayo sequence, Breakdancers sequence and Ballet sequence. The above three video sequences are 50 frames, 100 frames and 100 frames respectively, and the resolutions are 640×480, 1024×768 and 1024×768. Akko&Kayo The coding viewpoints of the sequence are viewpoint 27 and viewpoint 29, and the coding viewpoints of Breakdancers sequence and Ballet sequence are both viewpoint 0 and viewpoint 2.
[0039] see figure 2 , a kind of edge-based coding method of the depth video drawn for virtual view of the present invention, its steps are:
[0040](1), edge detection: use the Sobel edge detection algorithm to process the macroblock (Microblock, MB) of the depth map, a...
