Log image was acquired by X-ray real-time digital imaging system without log destruction. This paper presents the average density value of the specific spot of log is measured quickly and exactly according to log perimeter and log image information using the method of artificial neural network. According to the basic knowledge of X-ray testing technique, the method of getting high quality digital...
Automatic alignment design is always one pursuing goal of highway geometric designers with the rapid development of modern technologies such as intellection, digitalization and automatization. Because of the fact that artificial neural network is widely used in the field of pattern recognition, an approach to fit some control points and then to determine the appropriate type of horizontal curves based...
Contrasting to the original method of identifying the types of wood defects which requires the experienced technical staff with good discrimination to consider the characteristics of wood defects in the image, this paper presents a new method which can identify the types of internal wood defects rapidly and accurately by BP neural network which can analyse the visual characteristics parameters of...
