Ambiguous Digitizations by Dilation
نویسندگان
چکیده
This article deals with ambiguous surface digitizations by dilation in n-dimensional space. The digitization of a sufficiently regular surface is separating but not necessarily minimal. We will determine conditions under which the supercover and the grid intersection digitizations are discrete surfaces. It will also be proven that non-overlapping domains do not solve the problem of simple points in digitizations. No matter how the digitization domain is chosen there will occur ambiguous cases which have to be treated differently.

Study on the Digitization Dual Combinatorics and Convex Case
The action of a translation on a continuous object before its digitization generates several digitizations. The dual, introduced by the authors in a previous paper, stands for these digitizations in function of the translation parameters. This paper focuses on the combinatorics of the dual by making a link between the digitization number and the boundary curve, especially through its dual repre...
متن کاملWeak colored local rules for planar tilings
A linear subspace E of R has colored local rules if there exists a finite set of decorated tiles whose tilings are digitizations of E. The local rules are weak if the digitizations can slightly wander around E. We prove that a linear subspace has weak colored local rules if and only if it is computable. This goes beyond the previous results, all based on algebraic subspaces. We prove an analogo...
متن کاملPupil dilation reflects perceptual selection and predicts subsequent stability in perceptual rivalry.
During sustained viewing of an ambiguous stimulus, an individual's perceptual experience will generally switch between the different possible alternatives rather than stay fixed on one interpretation (perceptual rivalry). Here, we measured pupil diameter while subjects viewed different ambiguous visual and auditory stimuli. For all stimuli tested, pupil diameter increased just before the report...
متن کاملVirtual Three- Dimensional Analysis of Digitized Dental Impressions and Stone Replicas
In response to increasing patient awareness of esthetic dental rehabilitation, the preference today is for all-ceramic restorations, which show superior biocompatibility and similar light characteristics to the natural tooth. The fit of a dental restoration depends on quality throughout the entire manufacturing process. The final result is affected by multiple factors, such as preparation of th...
متن کاملA Defense of Imprecise Credences in Inference and Decision Making1
Some Bayesians have suggested that beliefs based on ambiguous or incomplete evidence are best represented by families of probability functions. I spend the first half of this essay outlining one version of this imprecise model of belief , and spend the second half defending the model against recent objections, raised by Roger White and others, which concern the phenomenon of probabilistic dilat...
