Abstract
With the development of information technology more and more rapidly, the development of computer intelligent image recognition technology is also becoming more and more perfect, and its function is more and more important. This paper is based on the neural network method, the intelligent computer image recognition technology is studied in this paper, genetic algorithm and GA BP algorithm are combined, through the analysis of intelligent image recognition principle, image pattern recognition and BP neural network learning algorithm, a GA-BP network model for image recognition. The four layer neural network, the input node is set to 256, the output node is set to 5, conducted a comparative experiment of GA-BP and BP neural network. The results show that the digital image recognition, the correct recognition rate is up to 98.7% GA-BP network BP network, the correct recognition rate was 92.5%, the GA-BP network recognition rate is up to 6.2% compared with BP network, GA-BP network to overcome the slow convergence of BP network and the shortcomings of long training time.
