Polyhedral mesh surfaces are widely utilized to represent objects reconstructed from 3D ranged images. In computer-aided engineering, it is desired to not only observe but also me...
Cortical amplification is a mechanism for modifying the selectivity of neurons through recurrent interactions. Although conventionally used to enhance selectivity, cortical amplif...
Regular structures, flat and non-flat, are perceived as regular in a wide range of viewing angles and under varying illumination. In this papers, we exploit this simple observatio...
This paper proposes to use zooming function of digital cameras for robust character recognition and to control focal length for improving the performance even in dim light conditi...
In this paper, we propose a novel type of 3-D scanning system named ‘Ladder-type laser scanning system,’ designed for scanning vertical and narrow areas. Two line scanners are...
