A Temporal Regularizer for Large Optical Flow Estimation

2006 International Conference on Image Processing, 2006
The aim of this work is to propose a model for computing the optical flow in a sequence of images with a spatio-temporal regularizer explicitly designed for large displacements. We study the introduction of a temporal regularizer that expands the information beyond two consecutive frames.

Multiple Combined Constraints for Optical Flow Estimation

2007
Several approaches to optical flow estimation use differential methods to model changes in image brightness over time. In computer vision it is often desirable to over constrain the problem to more precisely determine the solution and enforce robustness.

Optical Flow Estimation Using Genetic Algorithms

2006
This paper illustrates a new optical flow estimation technique, which builds upon a genetic algorithm (GA). First, the current frame is segmented into generic shape regions, using only brightness information. For each region a two-parameter motion model is estimated using a GA.
