Research for automatic recognition for vehicle based on improved BP network

In this article, BP network learning algorithm is improved by using momentum and genetic algorithm after analyzing the defects of the BP network learning algorithm. Wavelet multi-scale edge detection is used to segment the vehicle image and extract the feature of the image. And then the features of moment invariants and improved BP neural network models are used to automatically recognize and classify the vehicle image. This algorithm can improve the speed and accuracy for the automatic identification and classification of the vehicle.
