Shape Deformation
In physics, deformation is a change of a shape due to an applied force. Investigating shape deformation can reveal the transformation between two similar shapes and give information about local and global shape differences. Mathematically, a deformation is defined as a mapping from a shape t to y by a transformation function Φ, i.e. .(See Definition 10.2 of I.L. Dryden and K.V. Mardia (1998). Statistical Shape Analysis.

Famous quotes containing the word shape:
“The poet will prevail to be popular in spite of his faults, and in spite of his beauties too. He will hit the nail on the head, and we shall not know the shape of his hammer. He makes us free of his hearth and heart, which is greater than to offer one the freedom of a city.”
