杂货店数据集,包含了层级归类信息、视觉信息和语义标签。包含了自然场景和独立的图像，共有81个细粒度的分类和5125张图像，每类包含30-138张。（from 瑞典皇家理工 微软剑桥）
粗分类和细分类：
用于评测的分类方法：
同时还进行了从自然图像到独立图像间的编码解码生成：

GeoNet，第一个基于点云来为物体表面固有(Geodesic)结构建模的神经网络。研究人员提出了一种融合机制利用GeoNet与基础网络结合起来对点云进行分析。这篇文章提出了GeoNet来从点云数据中学习出表面拓扑形态的表示方法，并用测地线(geodesic)融合的方法对学习到的形态学特征进行分析和利用。(from UCLA Face++ 斯坦福 UIUC)
其中GeoNet，测地线邻域估计网络的结果如下图所示，基于自编码器抽取每点特征并利用测地线匹配来作为核函数，通过学习到的嵌入特征来估计测地线的邻域信息。GM层的中间特征包含了丰富的点云形态和表面信息。：
下图是测地线融合机制，可用于点云加密上采样、法向量重建和非刚体的形状分类等。
与PU-Net融合后点云上采样的结果：
与PointNET++融合后法向量估计和泊松表面重建结果。
