متن کاملA spectral 2-D Wold decomposition algorithm for homogeneous random fields
The theory of the 2-D Wold decomposition of homogeneous random elds is eeective in image and video analysis, synthesis, and model-ing. However, a robust and computationally ef-cient decomposition algorithm is needed for use of the theory in practical applications. This paper presents a spectral 2-D Wold decomposition algorithm for homogeneous and near homogeneous random elds. The algorithm reli...
متن کاملA Smale-Like Decomposition for Discrete Scalar Fields
In rhis papec we address rhe problem of represenring rhe srmrure of the ropology of a d-dimensional scalar field LIS a basis for consrrucring a mulriresolurion represenrarion of rhe srrucrure of such afield. To rhis aim, we define a discrere decomposirion of a rriangulared d-dimensional domain, on whose verrices rhe values of rhefield ure given. We exrend a Smale decomposirion. defined by Thom ...
متن کاملOptimization of Discrete Markov Random Fields via Dual Decomposition
A new message-passing scheme for MRF optimization is proposed in this paper. This scheme inherits better theoretical properties than all other state-of-the-art message passing methods and in practice performs equally well/outperforms them. It is based on the very powerful technique of Dual Decomposition [1] and leads to an elegant and general framework for understanding/designing message-passin...
