Processes at Discontinuities
نویسندگان
چکیده
Leyton [1988] developed a set of rules by which process-history can be recovered from smooth natural shapes such as out l ines of tumors, clouds, or islands. In this paper, we extend this analysis to deal w i t h shapes w i t h first-order discontinuit ies such as corners, creases and cusps. A simple extension to the notat ion al lows one extra rule to cover most of these phenomena.

Extremal Processes with One Jump
Convergence of a sequence of deterministic functions in the Skorohod topology d 0;? implies convergence of the jumps. For processes with independent additive increments the ®xed discontinuities converge. In this paper it will be shown that this is not true for processes with independent max-increments. The limit in d 0;? of a sequence of stochastically continuous extremal processes may ha...
متن کاملConvergence of Random Processes without Discontinuities of the Second Kind and Limit Theorems for Sums of Independent Random Variables
Let £,(<).£,(/), • • • and {(/) be random processes on the interval [0, 1], without discontinuities of the second kind. A. V. Skorohod has given necessary and sufficient conditions under which the distribution of /(C(0) converges to the distribution of /({(/)) as n -» oo for any functional / continuous in the Skorohod metric. In the following we shall consider only stochastically right-continuo...
متن کاملMultiresolution discontinuity-preserving surface reconstruction
This paper proposes a single multiresolution framework for both surface "tting and discontinuities identi"cation in the surface reconstruction problem. In particular, the Mallat}Zhong wavelet transform modulus maxima (WTMM) representation is employed for representing the surface which allows the discontinuity detection and surface "tting to be carried out simultaneously in a cooperative manner ...
متن کاملHysteresis, cooperativity, and depth averaging in dynamic random-dot stereograms.
Experiments were performed to assess the response of the human visual system to dynamic random-dot patterns composed of disparity mixtures. In Experiment 1, the perceived depth and relative stability of two patterns were compared; one pattern depicted two transparent layers of dots, and the other depicted a volume of dots. Two effects were found: (1) the volume pattern exhibited a large degree ...
متن کاملTomaso Poggio Integrating vision modules with coupled MRFs
I outline a project for integrating several early visual modalities based on coupled Markov Random Fields models of the physical processes underlying image formation, such as depth, albedo and orientation of surfaces. The key ideas are: a) to use as input data estimates of the various processes and their discontinuities, computed by several different algorithms. b) to implement with MRFs the ph...
متن کاملOptimal simultaneous replacement and maintenance of a machine with process discontinuities
— In gênerai, most pièces ofequipment tend to become less efficient productively as their âge increases, until they reach a point where it is no longer deemed profitable to use them. However, the obsolescence of a machine is usually Hmited to a particular production process. This paper is concerned with productive obsolescence of machines^ which is defined as process discontinuities. These usua...
