New Estimate Geometric Transformation block with
RANSAC and Least Median of Squares Algorithms
The Estimate Geometric Trans form ation block can be used to find the
transformation matrix which maps the greatest number of point pairs between
two images. The user can select to use the RANdom SAmple Consensus
(RANSAC) or the Least M edian of Squares algorithms to calculate the
distance metric for finding the transformation matrix. For more information
see the Estimate Geometric Transformation block reference page.
