摘要: Graph matching is a fundamental problem with many applications in computer vision. Patterns are represented by graphs and pattern recognition corresponds to finding correspondence between vertices from different graphs. In cases, the can be formulated as quadratic assignment problem, where cost function consists of two components: linear term representing vertex compatibility encoding edge compatibility. The NP-hard present paper extends approximation technique based on graph efficient belief propagation, described previous work, using sparse representations for shape matching. Successful results 3D objects handwritten digits illustrated, COIL MNIST datasets, respectively.
