The paper presents a technique for grouping edges around a given visual fixation point. By giving the fixation point and a starting position, the edge grouping problem becomes a sequential search, and can be efficiently implemented with dynamic programming. By providing multiple fixation points, the method can explore the scene in a more flexible and context driven manner. The paper proposes a method...
The aim of this study is to generate a standard ship's navigator's decision-making and action model that might become one index for safety navigation and navigational education area. It is important for a navigator to avoid targets and secure a navigation space for the prevention of collision. In this study, a navigator' decision-making and action for avoidance is focused and navigator's decision-making...
We propose a parallel phase-shifting digital holography capable of simultaneously capturing both outside three-dimensional (3D) information of the object such as a surface of an object which human being can perceive (visible information) and internal 3D information of the object (invisible information) using a visible laser light and an invisible laser light. This technique can carry out phase-shifting...
We present a two-step iterative algorithm to estimate the trajectory of a hopping rover. In the first step, a monocular scheme of visual odometry is adapted to estimate an initial portion the hopping trajectory. From this, the parameters for the ballistic motion are recovered, and the trajectory is extrapolated to predict the positions of the rover for the remainder of the hop. In the second step,...
