We present a multiview image completion method that provides geometric consistency among different views by propagating space structures. Since a user specifies the region to be completed in one of multiview photographs casually taken in a scene, the proposed method enables us to complete the set of photographs with geometric consistency by creating or(More)
Various types of robots have been built and used in our daily life for various purposes. One of them is an assistive robot that can autonomously perform a proper task in a given situation. The robot is required to integrate constituent algorithms into one controlled architecture for the autonomous operation. In this paper, we categorize the constituent(More)
The performance of depth reconstruction in binocular stereo relies on how adequate the predefined baseline for a target scene is. Wide-baseline stereo is capable of discriminating depth better than the narrow-baseline stereo, but it often suffers from spatial artifacts. Narrow-baseline stereo can provide a more elaborate depth map with fewer artifacts,(More)
In this paper, an arm trajectory generation method based on the Rapidly-Exploring Random Tree Star (RRT*) is proposed for humanoid robot. The RRT* is one of anytime motion planning algorithms. The RRT* adopts the three fundamental components from the RRT, the preceding version of RRT*: the state variables, local planner, and cost function. The end effector(More)
Humanoid robot requires a robust prevention system against external disturbances to protect itself from falling to the ground and to perform its tasks completely. In this paper, a Falling Prevention System for humanoid robot is proposed to avoid falling from the disturbances, and helps humanoid robot recover its balance from external force by taking a step.(More)
This work reports electrothermal MEMS parallel plate-rotation (PPR) for a single-imager based stereoscopic endoscope. A thin optical plate was directly connected to an electrothermal MEMS microactuator with bimorph structures of thin silicon and aluminum layers. The fabricated MEMS PPR device precisely rotates an transparent optical plate up to 37° prior to(More)
