Feature extraction and classification recognition are very important for surface defect recognition of strip steel. Traditional methods of feature extraction and defect recognition cannot take into account both the recognition accuracy and the running time. In order to solve the above two problems, a novel feature extraction and recognition method are proposed in this paper. On the one hand, a semi-supervised...
The design of CRT controller is studied, which is applied in the Speech Interactive System based on ASIC. CRT controller based on CPLD is presented. MCU flexible read and write to RAM with CPLD. Meanwhile, the simulation is also given based on Maxplus II. The simulating results prove that the design can reach the demand of real time exchanging, and has integrality, reliability and good applications...
Information is the organic unity of two consitute elements—the form and the content. Information exchange including two aspects, which are the content expression by using of the form and the content acception by using of the form. Thew expression on information content mustin the form of understanding and acception based on the knowledge and experience of the recipients. The content of location information...
