Method, system and computer program product for registration of multi-dimensional datasets

摘要

Methods, systems and computer program products for estimating changes in an object represented by first and second multidimensional datasets. The first dataset is a reference dataset and the second dataset is an altered dataset. Discrete data samples of the first dataset are processed to form a piecewise continuous representation thereof. An error function is computed for comparisons between discrete data samples in the second dataset and the piecewise continuous representation of the first dataset. An alteration of the second dataset relative to the first dataset that minimizes the error function is determined.
