The cartoon animation filter
- ACM Transactions on Graphics
, 2006
"... We present the ”Cartoon Animation Filter”, a simple filter that takes an arbitrary input motion signal and modulates it in such a way that the output motion is more ”alive ” or ”animated”. The filter adds a smoothed, inverted, and (sometimes) time shifted version of the second derivative (the accele ..."

Experimental results show that the filtered motion exhibits anticipation, follow-through, exaggeration and squash-and-stretch effects which are not present in the original input

Anticipative Calculus for Filtered Poisson Processes
"... We construct the basis of a stochastic calculus for a new class of processes: filtered Poisson processes. These processes are defined by an fBm-like stochastic integral but a Poisson process is subsided to the Brownian motion. We use Malliavin calculus to first construct a gradient then a divergence ..."

Touchscreen User Motion Anticipation for Usability Improvement
"... Abstract — This paper proposes a method for improving touchscreen usability by anticipating user motions. Reaction speed and simple structure are important for good touchscreen usability. With this in mind, we present a system that can estimate a desired position for user motion by anticipating a mo ..."

Active filtering of physiological motion in robotized surgery using predictive control
- IEEE Transactions on Robotics
, 2005
"... Abstract — This paper presents a predictive control approach to active mechanical filtering of complex, periodic motions of organs induced by respiration or heart beating in robotized surgery. Two different predictive control schemes are proposed for the compensation of respiratory motions or cardia ..."

Video-Based Tracking of Single Molecules Exhibiting Directed In-Frame Motion
"... Abstract: Trajectories of individual molecules moving within complex environments such as cell cytoplasm and membranes or semiflexible polymer networks provide invaluable information on the organization and dynam-ics of these systems. However, when such trajectories are obtained from a sequence of m ..."

of microscopy images, they can be distorted due to the fact that the tracked molecule exhibits appreciable directed motion during the single-frame acquisition. We propose a new model of image formation for mobile molecules that takes the linear in-frame motion into account and develop an algorithm based
Particle Filtering for

"... circa 53,000 words Real-time camera localisation is becoming increasingly important in wearable computing, particularly for applications such as augmented reality. These systems involve human interaction and therefore movement of the camera exhibits an intrinsic level of unpredictability which makes ..."

and argue that topdown Bayesian filtering is the most sensible approach to real-time localisation. Such failures are often caused by rapid, unpredictable, or erratic motions such as severe camera shake and prolonged occlusions. We are able to demonstrate that the particle filter performs significantly
A Matched-Filter Method For Motion-Compensated Spotlight-Mode Sar Processing
"... We present a SAR azimuth processing technique for alleviating motion effects. Our proposed approach may be viewed as a D-dimensional matched-filter (D ? 2), whose parameters are determined by the relative motion between the SAR antenna and the target. In contrast to similar multi-dimensional matched ..."

Spike Frequency Adaptation Implements Anticipative Tracking in Continuous Attractor Neural Networks
"... To extract motion information, the brain needs to compensate for time delays that are ubiquitous in neural signal transmission and processing. Here we propose a simple yet effective mechanism to implement anticipative tracking in neural sys-tems. The proposed mechanism utilizes the property of spike ..."
