Abstract
The Dynamic Pyramid is a model to solve the correspondence problem of image sequences. A robust estimation of local displacements is combined with controlled continuity constraints. At the heart of the model is the functional of an elastic membrane whose elastic constants are subject to variation. The continuity control function is derived from the tension in the displacement vector field at grayvalue edges. The displacement term of the functional is based on robust local binary correlations derived from the signs of the bandpass filtered images. The basic representation of the model is the pyramid: The original images are converted into Laplacian pyramids, the signs of which are the features to determine the local displacements as well as the continuity control function. The vector field is built up as a pyramid from coarse to fine, giving the final displacement vector field at the finest level.
