Abstract
This paper presents machine-printed character recognition acquired from license plate using convolutional neural network (CNN). CNN is a special type of feed-forward multilayer perceptron trained in supervised mode using a gradient descent Backpropagation learning algorithm that enables automated feature extraction. Common methods usually apply a combination of hand-crafted feature extractor and trainable classifier. This may result in sub-optimal result and low accuracy. CNN has proved to achieve state-of-the-art results in such tasks such as optical character recognition, generic objects recognition, real-time face detection and pose estimation, speech recognition, license plate recognition etc. CNN combines three architectural concept namely local receptive field, shared weights and subsampling. The combination of these concepts and optimization method resulted in accuracy around 98%. In this paper, the method implemented to increase the performance of character recognition using CNN is proposed and discussed.
