چکیده

This paper presents a robust vision system for lighting fluctuation for a parts positioning robot by means of dynamic range expansion of a video camera. The vision system was confirmed by experiments to stably detect the position of the object, in comparison to a conventional method, even if the light environment dynamically varies. The above result revealed that the dynamic range expansion of a video camera is very effective for realizing a robust vision system against the fluctuation of a light environment.

A Fast, Robust, Automatic Blink Detector

Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
