摘要:Depth propagation plays an important role to improve the quality of converted video in 2D-to-3D conversion. During depth propagation, the propagation path is usually along the time. In this paper, a new depth propagation algorithm is proposed to improve the quality of depth propagation by changing the propagation path according to frame clustering. The frames are clustered via K-means clustering based on HSV color histogram. The frame at the center of each cluster is selected as the keyframe of the cluster and the other frames are taken as the non-keyframes attaching to the keyframe. The depth information of keyframe is propagated to the non-keyframes within the same cluster directly. The performance of the proposed depth propagation algorithm is evaluated by MSE of the propagated depth map comparing with several existing algorithms. The comparison results show that the depth propagation errors can be reduced a lot by the proposed clustering based propagation.
