The hybrid constraint equation for motion extraction
Image and Vision Computing, 1989Abstract A new derivation of the constraint equation for motion extraction in the image flow is presented. The derivation was obtained by applying the constraint equation to the Fourier transform of the 2D images. It resulted in a hybrid equation joining time-space and frequency notations.

Hybrid video using motion estimation
SMC 2000 Conference Proceedings. 2000 IEEE International Conference on Systems, Man and Cybernetics. 'Cybernetics Evolving to Systems, Humans, Organizations, and their Complex Interactions' (Cat. No.00CH37166), 2002One of the major problems in low-bandwidth telerobotics applications is determining what visual data is sufficient to allow the operator to successfully perform a task. When the available bandwidth is extremely low, we must severely restrict the data being transmitted.

Hybrid architecture for understanding motion sequences
Neurocomputing, 1993Abstract The aim of the research introduced in this paper is the development of a hybrid vision system architecture based on a unified neural network platform and a query-based database that shares their noise-tolerant, learning and interactive properties.

A hybrid approach for complete motion planning
2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007We present an efficient algorithm for complete motion planning that combines approximate cell decomposition (ACD) with probabilistic roadmaps (PRM). Our approach uses ACD to subdivide the configuration space into cells and computes localized roadmaps by generating samples within these cells.

HSfM: Hybrid Structure-from-Motion
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017Structure-from-Motion (SfM) methods can be broadly categorized as incremental or global according to their ways to estimate initial camera poses. While incremental system has advanced in robustness and accuracy, the efficiency remains its key challenge.

A hybrid motion cueing algorithm
Control Engineering Practice, 2020Abstract Current closed-loop, optimization-based motion cueing algorithms (MCAs) use a driver model to predict a future driving dynamics reference. These models are often inaccurate and/or computationally expensive because future driving behaviour is unknown. In some cases, the vehicle’s trajectory is known in advance.

A Voronoi-based hybrid motion planner
Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems. Expanding the Societal Role of Robotics in the the Next Millennium (Cat. No.01CH37180), 2002We present a hybrid path planning algorithm for rigid and articulated bodies translating and rotating in a 3D workspace. Our approach generates a Voronoi roadmap in the workspace and combines it with "bridges" computed by a randomized path planner with Voronoi-biased sampling.

Segmentation of hybrid motions via hybrid quadratic surface analysis
Tenth IEEE International Conference on Computer Vision (ICCV'05) Volume 1, 2005In this paper, we investigate the mathematical problem underlying segmentation of hybrid motions: given a series of tracked feature correspondences between two (perspective) images, we seek to segment and estimate multiple motions, possibly of different types (e.g., affine, epipolar, and homography).

Hybrid Hierarchical Motion Planning
AIAA Guidance, Navigation and Control Conference and Exhibit, 2008In this paper, the problem of motion planning of an autonomous agent in an uncertain environment is solved in a hierarchical fashion. At the higher level of the hierarchy, the state-space of the agent is reduced to a set of “landmarks” through the use of suitably defined control policies at the lower level, called “options”, which results in a semi ...

Thermocapillary motion of hybrid drops
Physics of Fluids, 2008Hybrid drops are composed of two or more immiscible phases. They occur in various natural and technological processes and environments, e.g., the atmosphere, liquid membranes, and liquid bilayers and direct-contact heat and phase separation processes. In this work we have studied the dynamics of an axisymmetric hybrid drop in an infinite viscous domain.
