The parameter estimation to mixture models has been shown as a local optimal solution for decades. In this paper, we propose a functional estimation to mixture models using step functions. We show that the proposed functional inference yields a convex formulation and consequently the mixture models are feasible for a global optimum inference. The proposed approach further unifies the existing isolated...
In this paper, the problem of concealing missing image/video blocks is casted into a framework of Bayesian estimation. The conditional expectation of the missing block vector is taken over a pilot vector of correctly decoded pixels near the missing block. Multiple observations of the missing vector and pilot vectors obtained in a nonlocal manner are used to approximate the expectation. We design a...
In this paper, we propose a novel method of motion segmentation through image sequence. In our work, no assumptions of boundary densities, color, or textures are made about the background or the object. Neither do we assume any special motion model to the background or the object. With the help of classic Bayesian theory, an energy function describing the piece-wise smooth motion field of the image...
