Research on digital image recognition system based on multiple invariant moments theory and BP neural network
Han Jian-ning, Mingquan Wang · 2010
Based on the pattern recognition theory, principle processes of a digital image are described. To achieve de-noising, sharpening, binary transformation, edge extraction and other image processing of digital image, the image recognition system was programmed in C language. The system calculates the seven invariant moments as all characters of an image, recognizes an image by BP neural network.
