Qiushi Bai, Limeng Zhao, Yunzhou Zhang, Zixin Qi · 2010
With the rapid development of intelligent building, the requirement of automatic recognition of digital meter reading is increasingly urgent. Based on image processing, this article uses iterative global threshold to binarize the images and then adopts projection method to locate the target regions and divide the numbers. Features are extracted and back-propagation neural network is used to read the numbers automatically and contributes to a high accuracy of recognition rate.
