What does it mean for a deformation to be admissible in LDDMM?
Choose one option.
Show answer
- B. It satisfies the problem constraints, such as bringing the template to the target
Explanation
An admissible deformation belongs to the class \(\mathcal{A}\), meaning it respects the problem constraints. Only among them is the minimum energy sought.
Review the concept: Minimum energy
The minimum energy \(E_{\min}\) is the lowest cost among admissible deformations; in LDDMM it measures how much effort the field generating the transformation requires.
\[E_{\min}=\min_{\varphi\in\mathcal{A}}E(\varphi)\]
