Shadowing and structural stability for operators
Ergodic Theory and Dynamical Systems, 2020A well-known result in the area of dynamical systems asserts that any invertible hyperbolic operator on any Banach space is structurally stable. This result was originally obtained by Hartman in 1960 for operators on finite-dimensional spaces.

On shadowing: Ordinary and ergodic [PDF]
Journal of Mathematical Analysis and Applications, 2010 The aim of this paper is to introduce the notion of ergodic shadowing for a continuous onto map which is equivalent to the map being topologically mixing and has the ordinary shadowing property. In particular, we deduce the chaotic behavior of a map with

Shadow Removal Based on Shadow Direction and Shadow Attributes
2006 International Conference on Computational Inteligence for Modelling Control and Automation and International Conference on Intelligent Agents Web Technologies and International Commerce (CIMCA'06), 2006Moving shadow removal is critical for robust moving object tracking system. A shadow removal algorithm based on shadow attributes is presented in this paper. The direction of shadow is estimated first, and then shadow points are sampled based on the direction of shadow. At last the shadow attributes is calculated using the sampled shadow points.

Shadowing: What is It? How to Use It. Where Will It Go?
RELC Journal : A Journal of Language Teaching and Research in Southeast Asia, 2018Twenty-five years have passed since a teaching technique, called shadowing, was introduced in Japanese EFL contexts. Recently, this technique has gradually been recognized around the world. Given that many studies have been published about shadowing, the

HumanPlus: Humanoid Shadowing and Imitation from Humans
Conference on Robot LearningOne of the key arguments for building robots that have similar form factors to human beings is that we can leverage the massive human data for training. Yet, doing so has remained challenging in practice due to the complexities in humanoid perception and

Shadows are visual objects and as such are subject to preference rules for segmenting the visual scene (such as Gestalt laws). These rules govern shadows along two dimensions: their general unity and individuation (eg they describe a certain area as a unitary shadow as opposed to a set of two distinct shadows), and their being the of a given object, as

The shape of an object may be estimated by observing the shadows on its surface. We present a method that is robust with respect to a conservative classification of shadow regions. Assuming that a conservative estimate of the object shape is available, we analyze images of the object illuminated with known point light sources taken from known camera ...

A bilingual pediatrician is afforded an unusual window into the lives of America's illegal immigrants: though they're shut out of our health care system, their American-born children are eligible for Medicaid, so they tell the pediatrician their stories and seek advice.
