An adaptive scheme for estimating motion
2004 International Conference on Image Processing, 2004. ICIP '04., 2005In this paper, we propose a new scheme for estimating the motion adaptively at each pixel. We assume non-stationary statistics for noise and motion, and propose a blind approach based on using the generalized cross validation (GCV) technique. We thus determine a different level of regularization at each pixel based on the local statistics using GCV ...

Adaptive motion tracking for fast block motion estimation
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002In this paper, an adaptive motion tracking method is proposed to provide an accurate predictive motion vector for the block matching algorithm to locate the search origin by exploiting the high motion correlation in both the temporal and spatial domain.

Adaptive Motion Data Representation with Repeated Motion Analysis
IEEE Transactions on Visualization and Computer Graphics, 2011In this paper, we present a representation method for motion capture data by exploiting the nearly repeated characteristics and spatiotemporal coherence in human motion. We extract similar motion clips of variable lengths or speeds across the database. Since the coding costs between these matched clips are small, we propose the repeated motion analysis

Mobile robots are increasingly being deployed in the real world in response to a heightened demand for applications such as transportation, delivery and inspection. The motion planning systems for these robots are expected to have consistent performance across the wide range of scenarios that they encounter.

Adaptive prediction of respiratory motion for motion compensation radiotherapy
Physics in Medicine and Biology, 2007One potential application of image-guided radiotherapy is to track the target motion in real time, then deliver adaptive treatment to a dynamic target by dMLC tracking or respiratory gating. However, the existence of a finite time delay (or a system latency) between the image acquisition and the response of the treatment system to a change in tumour ...

Segregation of motion aftereffect following adaptation to transparent motion
2004 IEEE International Joint Conference on Neural Networks (IEEE Cat. No.04CH37541), 2005Characteristics of motion aftereffect (MAE) following adaptation to two dot-populations moving in orthogonal directions at different speeds are reported. A test stimulus also consisted of two populations of randomly moving dots whose speeds were equal to the two adaptation speeds.

Adaptive motion compensation in MRI: Accuracy of motion measurement
Magnetic Resonance in Medicine, 1991AbstractIt has been shown that magnetic resonance image data can be corrected for the effects of motion by using retrospective adaptive techniques which employ navigator (NAV) echoes. We demonstrate the accuracy with which NAV echoes can measure motion, as well as the independent nature of the respective view‐to‐view and intraview corrections.

Motion Adaptation With Motor Invariant Theory
IEEE Transactions on Cybernetics, 2013Bipedal walking is not fully understood. Motion generated from methods employed in robotics literature is stiff and is not nearly as energy efficient as what we observe in nature. In this paper, we propose validity conditions for motion adaptation from biological principles in terms of the topology of the dynamic system.

Motion Compensation Assisted Motion Adaptive Interlaced-to-Progressive Conversion
IEEE Transactions on Circuits and Systems for Video Technology, 2004Block-wise processing of motion compensated interlaced-to-progressive conversion (MC-IPC) can cause spurious errors that degrade converted image quality significantly. This paper presents a novel IPC method based on motion adaptive IPC (MA-IPC) with its adaptation assisted by the motion compensation. The motion adaptation is performed with respect to a
