PROBLEM TO BE SOLVED: To solve a general kind of problem of low-level vision by sending a local evidence to an adjacent node in an inference stage and determining the maximum post-probability of scene estimation. SOLUTION: Training data 2 is an observation record of a known target. A display of discontinuity 11 or continuity 12 modeling the training data 2 is selected. The statistical relationship of the training data 2 is learnt by using the display of discontinuity 11 or continuity 12. Their relationship is represented as a mix of a vector, a matrix, or a Gaussian distribution. After the learning stage, inference is carried out as to the unknown target. A probability function Pd21 or Pc22 is used to infer one which is possibly a target 31 from the observation record 32 of the unknown target. This inference is carried out by locally transmitting the reliability through the Markov network.
