When a large-scale disaster occurs in control systems for social infrastructure, field equipment and control programs of the control systems might be lost. We have proposed the control system that operates control processing on cloud servers for rapi

In this paper, we develop an algorithm for navigating a mobile robot using the visual potential. The visual potential is computed from an image sequence and optical flow computed from successive images captured by a camera mounted on the robot, that

In this paper, we present an algorithm for the hierarchical recognition of an environment using independent components of optical flow fields for the visual navigation of a mobile robot. For the computation of optical flow, the pyramid transform of a

In this paper, we apply independent component analysis (ICA) to optical flow for the visual navigation of robots. Independent components of optical flow are used for motion cognition. In the medial superior temporal (MST) area of the brain, it is obs

Dominant plane is an area which occupies the largest domain in the image. In this paper, we develop an algorithm for dominant plane detection using the optical flow. The dominant plane estimation is an essential task for the autonomous navigation and

In this paper, we aim to develop an algorithm for featureless navigation of an autonomous robot using optical flow observed through a vision system mounted on a mobile robot. Furthermore, we show that this optical flow observed from a mobile robot fo

We develop a method for the optical flow computation from a zooming image sequence. The synchronisation of image resolution for a pair of successive images in an image sequence is a fundamental requirement for optical flow computation. In a real appl

We develop an algorithm to unify features extracted from a multichannel image using the Boolean function. The colour optical flow enables to detect illumination-robust motion features in the environment. Our algorithm robustly detects free-space for
