To solve the problem of huge computation in the solution process of using Hough Transform (HT), an improved HT algorithm based on Freeman criteria has been presented and used to locate window region for the envelope image successfully. The improved algorithm detects the whole image using a template with size of N*N and the center pixel of template, replacing other pixels in template, is calculated...
The Model Driven Architecture (MDA) concept and key technology were discussed, including modeling technology, model transformation technology and model template. A MDA framework using UML for Platform Independent Model (PIM) and XML for Platform Specific Model (PSM) was proposed for simulation system development. The main technology of the MDA framework was introduced, which included PIM modeling...
Electronic Travel Aid (ETA) technology can be used to help blind people walk. Blind users can judge current environment with the prompt of ETA system. The portable ETA system is a model of ETA system which is simple in structure, easy to carry, easy to use and low cost. One of the important research is how to extract the orientation of the blind sidewalk accurately. This paper using the methods of...
