这项工作的主要目标是讨论图像匹配/形状识别问题的可控性方法，这是许多应用中的一个重要问题，特别是医学应用。匹配问题被表述为涉及成本函数的近似可控性问题，其梯度是使用基于伴随方程的方法计算的。这项工作还讨论了图像匹配问题的时间离散版本。
The main goal of this work is to discuss a controllability approach to the image matching/shape identification problem, an important issue in many applications, medical ones in particular. The matching problem is formulated as an approximate controllability problem involving a cost functional whose gradient is computed using an adjoint equation based methodology. The time discrete version of the image matching problem is also discussed in this work.
