利用改进生成对抗网络进行人体姿态识别

针对人体模型中某些重要关节点准确定位的问题，提出了一种新型深度卷积生成对抗网络以进行静态图像中人体姿态的估计的方法。该方法采用了深度卷积的堆叠沙漏网络来准确提取图像上关键关节点的位置，该网络的生成和辨别部分被设计用于编码第一层次结构（亲本）与第二层次结构（子本）中的空间关系，并且展示了人体部位的空间层次。生成器和判别器在网络中被设计为两部分，并按照顺序连接在一起用来编码外观可能的关系，同时为人体部位存在的可能性以及身体的每个部分与其亲本部分之间的关系进行编码。在静态图像中，可以较准确地识别人体模型关键节点以及大致人体姿态。该方法在不同的数据集上进行了实验，在大部分情况下，提出的方法获得的结果优于其他几种对比方法。

Using Improved Generative Adversarial Network for Human Pose Estimation

Aiming at the problem of accurately locating some important joint points in human body modeling,a novel deep convolution generative adversarial network is proposed to estimate human poses from still images.Specifically,a stacked hourglass network with deep convolution network is used to accurately locate the key joint points in the images,the generative and the discriminative portions of the proposed adversarial deep neural network are designed to encode the spatial relationship between the parts in the first stage of the hierarchy(parents)and the parts in the second stage of the hierarchy(children).Each of the generator and the discriminator networks is designed as two components,which are sequentially connected together to infer rich appearance potentials and to encode not only the likelihood of the part’s existence but also the relationships between each body part and its parent.Finally,in the static images,the key nodes of the human body model and the approximate human poses can be estimated accurately.The method is tested on different data sets,in most cases,the results of the proposed method are better than those of other methods.
