This paper examines the gradient-based edge detection algorithm on hexagonal grids and compares it with that on conventional rectangular grids. Since there is no mature hardware for hexagonal-based image capture and ...

Accurately locating edge points is important for image measurement. This paper describes an edge detection method based on back-propagation algorithm of neural networks. A three-layer structure of artificial neural network ...

Gradient-based edge detection is a straightforward method to identify the edge points in the original greylevel image. It is intuitive that in the human vision system the edge points always appear where the greylevel value ...

After a decade of research and development, IP multicast has still not been deployed widely in the global Internet due lo many open technical issues: lack of admission control, poorly scaled with large number of groups. ...

Predictive frameworks for understanding and describing how animals respond to habitat fragmentation, particularly across edges, have been largely restricted to terrestrial systems. Abundances of zooplankton and meiofauna ...

The article presents the author's comment on the helpful and effective collegial relationships at workplaces. According to the author, the quality of their working lives is at least partially contingent on the quality of ...

The author focuses on patient experiences, family participation and professional roles in clinical nursing. She states that patient experiences and family participation are important in clinical nursing because it serves ...
