Spatio-Temporarily Consistent Video Disparity Estimation Algorithm
The proposed method shows superior speed, accuracy, and consistency compared to state-of-the-art algorithms. We have shown the method to be resilient even in large amounts of noise.Furthermore, we have illustrated that in general our method can be used to refine the results of any disparity estimation technique suffering from impulsive noise or estimation errors.
Our method can be used as a post-processing step to refine noisy estimates or to extend to videos.
We present a novel stereo video disparity estimation method. The proposed method is a two-stage algorithm. During the first stage, initial disparity maps are computed in a frame by-frame basis. In the second stage, the initial estimates are treated as a space-time volume.By setting up an l1-normed minimization problem with a novel three-dimensional total variation regularization, spatial smoothness and temporal consistency are handled simultaneously.
