Backward Behavior and Determining Functionals for Chevron Pattern Equations
Varga K. Kalantarov, Habiba V. Kalantarova, Orestis Vantzos
The paper is devoted to the study of the backward behavior of solutions of the initial boundary value problem for the chevron pattern equations under homogeneous Dirichlet's bounda…
Pattern formation in vector-valued phase fields under convex constraints
Orestis Vantzos
In this work, a new class of vector-valued phase field models is presented, where the values of the phase parameters are constrained by a convex set. The generated phase fields fea…
Temporally stable video segmentation without video annotations
Aharon Azulay, Tavi Halperin, Orestis Vantzos +2
Temporally consistent dense video annotations are scarce and hard to collect. In contrast, image segmentation datasets (and pre-trained models) are ubiquitous, and easier to label…
Endless Loops: Detecting and Animating Periodic Patterns in Still Images
Tavi Halperin, Hanit Hakim, Orestis Vantzos +6
We present an algorithm for producing a seamless animated loop from a single image. The algorithm detects periodic structures, such as the windows of a building or the steps of a s…
Chevron pattern equations: exponential attractor and global stabilization
H. Kalantarova, V. Kalantarov, O. Vantzos
The initial boundary value problem for a nonlinear system of equations modeling the chevron patterns is studied in one and two spatial dimensions. The existence of an exponential a…
Global Behavior of Solutions to Chevron Pattern Equations
H. Kalantarova, V. Kalantarov, O. Vantzos
Considering a system of equations modeling the chevron pattern dynamics, we show that the corresponding initial boundary value problem has a unique weak solution that continuously…
