ABSTRACT
This paper demonstrates that the visual and graphical repository can be established through extending the SVG standard, introducing C# script and customizing component into repository. The graphical system, which uses the technique of Visual Studio.Net, supports the secondary object-oriented development. It allows the user to not only add all kinds of component objects, but also add properties and functions for the object. In addition, the graphical system has a very good property of customization. It supports the C# script and the zoom in/zoom out of pictures. The file formats used in this system are XML and SVG.
ABSTRACT
This paper presents a recognition system for the automatic quality control in industrial applications. The purpose of the system is to collect the product information (e.g. Expiry-date, production identification) and verify these information for quality control. The main difficulties of the system are to make an effcient preprocessing for the acquired low resolution image and to create a simple and fast recognition method to get the product information. In this paper, we propose an effcient recognition method based on the endpoint features and structure characteristics of the numerals. The experimental results show that the proposed method is effcient, robust and reliable for recognizing machine printed numerals. The system is currently successfully working with a real application with required specifications.
ABSTRACT
Objective To accurately extract pulmonary vessels on medical images. Methods An efficient vessel segmentation framework is presented, which includes a smoothing method and a extraction algorithm. The smoothing method is based on an improved coherence diffusion approach that integrates the second-order directional differential information. It can analyze weak edges such as narrow peak or ridge-like structures. Meanwhile, an improved extraction algorithm is proposed. It is based on a fast marching algorithm where a sorted sequence array and multi-initialization technique are applied. Results The improved coherence diffusion approach can precisely preserve important oriented patterns and remove noises on the images. Experimental results on several images show that the proposed method can effectively find the location of pulmonary vessels. Conclusion The segmentation method is accurate and fast that can be a useful tool for medical imaging applications.
