Trifocal morphing

open access: yesProceedings on Seventh International Conference on Information Visualization, 2003. IV 2003., 2004
Image morphing allows smooth transition between 2D images. However, one of the limitations of existing image morphing techniques is the lack of interaction - the viewpoints of the interpolated images are restrained to the line joining the optical centers of the source and the destination images.

Near Stall Unsteady Flow Responses to Morphing Flap Deflections

open access: yesFluids, 2021
The unsteady flow characteristics and responses of an NACA 0012 airfoil fitted with a bio-inspired morphing trailing edge flap (TEF) at near-stall angles of attack (AoA) undergoing downward deflections are investigated at a Reynolds number of 0.62 × 106 ...

Analysis of Morphing Modes of Hypersonic Morphing Aircraft and Multiobjective Trajectory Optimization

open access: yesIEEE Access, 2019
Aiming at improving the range of wing-body combination aircraft at hypersonic flow conditions and exploring the application of morphing technology in hypersonic aircraft, morphing aircrafts with different morphing modes have been proposed.

The Functions of Phasic Wing-Tip Folding on Flapping-Wing Aerodynamics

open access: yesBiomimetics
Insects produce a variety of highly acrobatic maneuvers in flight owing to their ability to achieve various wing-stroke trajectories. Among them, beetles can quickly change their flight velocities and make agile turns.

The Control Efficiency Analysis of Asymmetry Transmutation forFolding Wing Morphing Aircraft

open access: yesHangkong gongcheng jinzhan, 2018
Folding wing morphing aircraft can alter their shape largely which causes the aerodynamic parameters change significantly. A control scheme that using asymmetric morphing as a control input is proposed in this paper to investigate the control efficiency ...

Morphing active contours

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 1999
A method for deforming curves in a given image to a desired position in a second image is introduced in this paper. The algorithm is based on deforming the first image toward the second one via a partial Differential equation, while tracking the deformation of the curves of interest in the first image with an additional, coupled, partial Differential ...

Graph Matching for Underwater Simultaneous Localization and Mapping Using Multibeam Sonar Imaging

open access: yesJournal of Marine Science and Engineering
This paper addresses the challenges of underwater Simultaneous Localization and Mapping (SLAM) using multibeam sonar imaging. The widely used Iterative Closest Point (ICP) often falls into local optima due to non-convexity and the lack of features for ...
