Embodiment
[0037] What this embodiment shows is a kind of fast decision-making method for the quadtree coding structure division of 3D video depth image, and its process is as follows figure 2 As shown, the steps include:
[0038] Step 1: Obtain the optimal prediction mode of the current coding block, the current coding block and the corresponding rate-distortion value through the traditional coding method;
[0039] Step 2: Determine whether the current coding block is the smallest coding unit: if yes, go to step 8; otherwise, go to step 3;
[0040] Step 3: Divide the current coding block into a quadtree structure, and repeat steps 4 to 7 for each obtained subsidiary coding block;
[0041] Step 4: Carry out the traditional coding method on the current auxiliary coding block, calculate the optimal prediction mode of the auxiliary coding block, and the corresponding rate-distortion value of the auxiliary coding block;
[0042]Step 5: If the current auxiliary coding block is the first on...
