在技术的发展中，脑部疾病的病例越来越多，提出了更多的治疗方法，并取得了积极的结果。但是，通过大脑质量，早期诊断可以改善成功治疗的可能性，并可以帮助患者更好地恢复治疗。源于这个原因，脑化是如今的医学图像分析中有争议的主题之一。随着体系结构的改进，提出了多种方法并获得竞争分数。在本文中，我们提出了一种将有效网络用于3D图像的技术，尤其是用于大脑质量分类任务解决方案的有效网络B0并达到竞争分数。此外，我们还提出了使用多尺度效率网络对MRI数据切片进行分类的方法

Let $\mathcal{D}$ be a dataset of smooth 3D-surfaces, partitioned into disjoint classes $\mathit{CL}_j$, $j= 1, \ldots, k$. We show how optimized diffeomorphic registration applied to large numbers of pairs $S,S' \in \mathcal{D}$ can provide descriptive feature vectors to implement automatic classification on $\mathcal{D}$, and generate classifiers invariant by rigid motions in $\mathbb{R}^3$. To enhance accuracy of automatic classification, we enrich the smallest classes $\mathit{CL}_j$ by diffeomorphic interpolation of smooth surfaces between pairs $S,S' \in \mathit{CL}_j$. We also implement small random perturbations of surfaces $S\in \mathit{CL}_j$ by random flows of smooth diffeomorphisms $F_t:\mathbb{R}^3 \to \mathbb{R}^3$. Finally, we test our automatic classification methods on a cardiology data base of discretized mitral valve surfaces.
