Deformation correction using Euclidean contour distance maps
Fons J. Verbeek · 2003
Utilizes the Euclidean distance transform as a tool for shape analysis and description. The author shows effective use of some (new) properties of the vector distance transform in determining parameters for a two-step transform of a distorted image to its undistorted equivalent. The transform is based on the outer contour of the object of interest as present in the image.>
