Neural network application to container number recognition

Abstract: This paper describes an application of neural network technology to a practical problemrecognition of container identification numbers. The general problem is described and technical difficulties are highlighted. A solution is propod and a set of algorithms are implemented. This paper focuses on the development ofthe character recognition algorithm, which usesa neural network model known as neocognitron. The general recognition methodology is discussed and the this neural network model can attain a high level … Show more

“…It is necessary to extract and recognize container identity automatically by image process and pattern recognition techniques. Though automatic container code recognition had been studied since 1990's [1,2], there were still many difficulties in container code recognition, especially in code detection and char extraction. The main difficulties come from: (1) Container code characters were painted with a wide range of sizes, fonts, colors, and spacing.…”

“…The neural network in the VECON system, which has been applied in a similar problem [4], acts as the character recognition module. Basically, it is a general feed-forward multi-layer perceptron with one hidden layer, trained by the back-propagation algorithm Given an input character pattern, the score of each output node resulted from the network operation describes the likeliness for the input to be regarded as the category associated with that node.…”

“…1 A three-line container number processing (identifying) truck and container ID numbers, a situation that has attracted our attention because of the potential of automating such a process. Many methods [1]- [4] have been proposed for character recognition but they are often subjected to substantial constraints. We have developed a practical vision system for vehicle and container ID numbers recognition called VECON.…”

“…These weights are also involved in the S-cell weight update process during supervised training (Algo- From the time that the neocognitron was first proposed, there appears to have been some level of confusion among experimenters as to how to calculate the masks for the S and C-cells. Some authors have chosen to omit reference to these weights altogether [93,118,132,165,183,184] others invent masks of their own [124,168]; only one person has suggested their irrelevance [77]. In an attempt to clarify the matter, two methods for calculating ct{i/) and d({i/) will be reviewed.…”
