Abstract: According to the characteristics of paper cut-out patterns exaggerative deformations，the seven moment invariants can be used as the eigenvector after the pretreatment of paper cut-out patterns image.The seven moment invariants normalized are input into BP neural network based on Levenberg-Marquardt algorithm and the trained network is used to be a classifier to realize the image pattern recognition.Experiments show that a relatively good recognition performance can be achieved to recognize paper cut-out patterns of exaggerative deformations.
