- W49483419 abstract "In this paper, we present a coherent Markov model for deformations of shapes based on the statistical distribution of the gradient vector field of the gray level and a probabilistic model for reduction of dimension. This allows us to infer the posterior distribution of deformations given the data. The localization of a shape in an image is then viewed as the minimizing of the corresponding Gibbs field. We use a stochastic optimization algorithm in order to find the optimal deformation, firstly with a simpler Gibbs field and then on the complete Gibbs field. This yields an unsupervised method for localization of shapes, provided that the image is not prohibitively too complex." @default.
