基于单张图片预测完整点云（from 阿姆斯特丹大学CV Lab）

模型如下所示：

首先通过2D RGB图生成出深度图，其作用在于规范2D-3D域之间的转换，并限制学习到的流型结构。同时基于深度图生成部分点云图,从像素坐标转到空间坐标
$Z[u,v,1]^T = K(R[X,Y,Z]^T+t)$
随后，通过在部分点云空间和完整点云空间的转化来获取点云。
在抽取部分点云特征矢量的基础上，利用类似PCN的方法实现了稀疏但完整点云的输出。（基于全连接，负责几何外形预测）
随后基于folding解码器来生成稠密点云（负责近似表面和局域形貌）
最后利用预测出的完整点云来约束部分点云的预测误差。
模型预测结果：

实际图像结果：
AutoFocus: Efficient Multi-Scale Inference,提出了一种高效的多尺度目标检测算法用于高效检测小物体。这种算法使用了由粗到精的策略，只在那些可能有小物体存在的区域使用细粒度的检测。为了得到这些区域，本文提出了一种称为FocusPixels的方法来预测小区域。同时为了配合FocusPixels高效的使用，研究人员给出了FocusChip来涵盖FocusPixels区域，以减少计算量。(from 马里兰大学)

上图所示，不同尺度的下，只有较小的大象被标记为FocusPixels

图像的处理流程如上图所示。

从单张图像恢复点云,主要将这一重建过程分解为图像到深度图、深度度通过相机模型到部分点云，再到稠密点云。
基于深度Inception生成网络的认知图像修复,这篇文章提出了方法克服了先前方法单一感受野的限制和人工痕迹的生成。多感受野可以改善图像特征的抽象能力，池化可以保持特征不变性。inception模块用于提取高层信息，并且利用了不同的mask数据集来提高修复模型的适应性。

包含inception模块的生成网络（from 同济）：

结果如下：

结果如图所示：

基于改进的WGAN实现语义图像修复（from University Pompeu Fabra）

得到结果如下：
