Accurate Real-Time Disparity Estimation with Variational Methods
2009Estimating the disparity field between two stereo images is a common task in computer vision, e.g., to determine a dense depth map. Variational methods currently are among the most accurate techniques for dense disparity map reconstruction. In this paper a multi-level adaptive technique is combined with a multigrid approach that allows the variational ...

Time-Dependent Perturbation-Variation Method. II
The Journal of Chemical Physics, 1964It is shown that the time-dependent perturbation-variation method recently developed by the author and that previously developed by Karplus and Kolker are equivalent.

Time-Dependent Perturbation—Variation Method
The Journal of Chemical Physics, 1963Through the use of the time-ordered perturbation expansion, an operator equation for the time-dependent perturbation problem, of the same form as occurs in the time-independent problem, is generated. Thus, a variational method can be used to study the time-dependent case as well as the time-independent case.

Real-Time Optic Flow Computation with Variational Methods
2003Variational methods for optic flow computation have the reputation of producing good results at the expense of being too slow for real-time applications. We show that real-time variational computation of optic flow fields is possible when appropriate methods are combined with modern numerical techniques. We consider the CLG method, a recent variational

A Total Variation Based Method for Multivariate Time Series Segmentation
Advances in Applied Mathematics and Mechanics, 2023Summary: Multivariate time series segmentation is an important problem in data mining and it has arisen in more and more practical applications in recent years. The task of time series segmentation is to partition a time series into segments by detecting the abrupt changes or anomalies in the time series.

Network Stratification Method by Travel Time Variation
Transportation Research Record: Journal of the Transportation Research Board, 2011There is a need for fair and statistically valid assessments of traveler information data services. For measurement of the accuracy of a traveler information service, ground truth data must be collected and compared with the data service being evaluated.

Genetic Variation in Human DNA Replication Timing [PDF]
Cell, 2014 SummaryGenomic DNA replicates in a choreographed temporal order that impacts the distribution of mutations along the genome. We show here that DNA replication timing is shaped by genetic polymorphisms that act in cis upon megabase-scale DNA segments.

Systems with Time Delay in the Calculus of Variations: The Method of Steps
IMA Journal of Mathematical Control and Information, 1988In ibid. 5, No.2, 125-145 (1988; Zbl 0655.49017), the author derived necessary and sufficient conditions for minima for the fixed-endpoint problem in the calculus of variations involving a constant delay in the phase coordinates. Here we convert, through the `method of steps' the delay problem into one without delay. Although this problem will not have
