Heading estimation is vital to everyday navigation and locomotion. Despite extensive behavioral and physiological research on both visual and vestibular heading estimation over more than two decades, the accuracy of heading estimation has not yet been systematically evaluated. Therefore human visual and vestibular heading estimation was assessed in the horizontal plane using a motion platform a...

acorn production plays a fundamental role in the organization and dynamics of oak forest ecosystems. regarding acorn importance, visual survey methods have been used to estimate acorn production of oak species throughout the world. in this study, the mast indices of brant`s oak (quercus brantii lindl.) were determined in a section of northern zagros forests, almost 36 ha area, near baneh, kurdi...

This paper investigates passivity-based visual feedback pose regulation whose goal is to control a vision camera pose so that it reaches a desirable configuration relative to a moving target object. For this purpose, we present a novel visual feedback estimation/control structure including a vision-based observer called visual motion observer under the assumption that a pattern of the target mo...
