Multi-Scale Spatial Feature-Guided Cloth Landmark Estimation

  • 摘要: 为了提高服装关键点检测的准确率,提出一种多尺度空间特征引导的服装关键点检测方法.首先,借鉴深度可分离卷积的思想,构建空间特征引导的注意力模块,在增强网络流中空间特征的同时,强化不同特征通道之间的信息交互;其次,将注意力模块嵌入HRNet网络的多个尺度上,在每个尺度上对输入特征的空间信息进行细粒度建模,从而更精确地定位关键点;然后,利用无偏数据增强方法,将数据从离散空间转换到连续空间,减小关键点检测过程中的量化误差;最后,采用由粗到细的训练策略,在提高关键点检测准确率的同时,大幅减少计算量.所提方法在DeepFashion2数据集的服装关键点检测任务中达到67.4%的准确率,超过文中对比方法.

     

    Abstract: In order to improve the accuracy of cloth landmark estimation, a method with feature-guided attention module is proposed. Drawing on the idea of depthwise separable convolution, the attention module is constructed, which not only enhances the spatial features in network, but also strengthens the information interaction between different feature channels. Then, it is put into each stage of the HRNet, so the spatial information of the input features could be modelled in a more granular way. Secondly, unbiased data processing is used, which converts the data from discrete space to continuous space, to reduce quantization error introduced by data argumentation. Finally, a coarse-to-fine training strategy is adopted which further reduce heavy computing costs and improve accuracy. The proposed method achieves the state-of-the-art result with 67.4% accuracy in DeepFashion2 dataset cloth landmark estimation task.
