The paper deals with adverse interactions between line stimuli in eccentric vision. Both contrast threshold and just noticeable difference of slant have been measured for a test line as a function of the distance from a number of surrounding lines. Test lines were either parallel or perpendicular to the surrounding lines. It turns out that the interference affects both contrast threshold and j....

0 Robot control using a real-time visual feedback has been recently improved (visual servoing.) Conventional vision systems are too slow for these application, because the CCD cameras are restricted to the video frame rate ( N T S C 30Hz, PAL 25Hz). To solve this problem, we have developed a 1ms vision system, to provide a far faster frame rate than that of the conventional systems. Our 1ms vis...

Rapid eye motion, or so called saccade, is a very quick eye motion which always occurs regardless of our intention. Although the line of sight (LOS) with saccade tracking is expected to be used for a new type of computer-human interface, it is impossible to track it using the conventional video camera, because of its speed which is often up to 600 degrees per second. Vision Chip is an intellige...

We present a portable active binocular robot vision architecture that integrates a number of visual behaviours. This vision architecture inherits the abilities of vergence, localisation, recognition and simultaneous identification of multiple target object instances. To demonstrate the portability of our vision architecture, we carry out qualitative and comparative analysis under two different ...

Computer Vision (CV) is a rapidly growing field, intent on enabling computers to process, analyze, and understand the information of images to produce structured information and/or make decisions. In recent years, interest in computer vision has grown in part as a result of both cheaper and more capable cameras, but also largely because of affordable and increasing levels of computer processing...
