Groupwise Image Alignment via Self Quotient Images
Sensors, 2020 Compared with pairwise registration, the groupwise one is capable of handling a large-scale population of images simultaneously in an unbiased way. In this work we improve upon the state-of-the-art pixel-level, Least-Squares (LS)-based groupwise image ...

Methods of Parallel Voxel Manipulation for 3D Digital Printing [PDF]
, 2007 A novel digital printing concept is explored for desktop fabrication of multimaterial objects with arbitrary 3D geometry. Digital objects are composed of many discrete, self-aligning voxels instead of continuous (analog) deposition techniques.

Surface tension-driven self-alignment
Soft Matter, 2017 Surface tension-driven self-alignment is a passive and highly-accurate positioning mechanism that can significantly simplify and enhance the construction of advanced microsystems. After years of research, demonstrations and developments, the surface engineering and manufacturing technology enabling capillary self-alignment has achieved a degree of ...

Self‐Aligned Anisotropic Plasmonic Nanostructures
Advanced Materials, 2019 AbstractGreat opportunities emerge not only in the generation of anisotropic plasmonic nanostructures but also in controlling their orientation relative to incident light. Herein, a stepwise seeded growth method is reported for the synthesis of rod‐shaped plasmon nanostructures which are vertically self‐aligned with respect to the surface of colloidal ...

Self-alignment of a Binocular Robot. [PDF]
Procedings of the British Machine Vision Conference 1995, 1995 We describe a novel method by which a four-axis binocular head platform can autonomously align its cameras so that their optic axes are parallel to each other and to the forward direction of the robot. The method uses controlled pans and elevations of the robot while viewing an unstructured scene to determine lines on the plane at infinity, whose ...

Intention Detection Using Physical Sensors and Electromyogram for a Single Leg Knee Exoskeleton
Sensors, 2019 In this paper, we present a knee exoskeleton. Due to the complicated structure of the knee, an exoskeleton can limit the wearer’s movement (e.g., when completely sitting down). To prevent this, the proposed exoskeleton is designed to move the ankle
