Curve Alignment by Moments
A significant problem with most functional data analyses is that of misaligned curves. Without adjustment, even an analysis as simple as estimation of the mean will fail. One common method to synchronize a set of curves involves equating “landmarks” such as peaks or troughs. The landmarks method can work well but will fail if marker events can not be identified or are missing from some curves. ...
متن کاملShape Matching by Curve Modelling and Alignment
Automatic information retrieval in the field of shape recognition has been widely covered by many research fields. Various techniques have been developed using different approaches such as intensity-based, modelbased and shape-based methods. Whichever is the way to represent the objects in images, a recognition method should be robust in the presence of scale change, translation and rotation. I...
متن کاملCurve Shapes: Comparison and Alignment
We present a method for identifying a partial match for twice differentiable curves. The method uses equal arc-length interval correspondences when comparing points on one curve to another. We use the square of difference in curvatures at each point to compare two curves, and find it to be fast enough for querying a large database of curves. Index Terms curve matching, partial matching, curvatu...
متن کاملMICA: Multiple Interval-based Curve Alignment
MICA enables the automatic synchronization of discrete data curves. To this end, characteristic points of the curves’ shapes are identified. These landmarks are used within a heuristic curve registration approach to align profile pairs by mapping similar characteristics onto each other. In combination with a progressive alignment scheme, this enables the computation of multiple curve alignments...
متن کاملJoint Probabilistic Curve Clustering and Alignment
Clustering and prediction of sets of curves is an important problem in many areas of science and engineering. It is often the case that curves tend to be misaligned from each other in a continuous manner, either in space (across the measurements) or in time. We develop a probabilistic framework that allows for joint clustering and continuous alignment of sets of curves in curve space (as oppose...
