唐卡是一种宗教卷轴画。作为藏族传统文化和宗教习俗的窗口,图像中重要语义对象的分割可以帮助公众理解图像内容,实现视觉内容的高层次语义认知。基于唐卡图像丰富的结构和规范的构图,提出了一种肖像类唐卡图像中心人物头饰的语义分割网络。同时,还构建了第一个唐卡图像中心人物头饰像素级语义标注数据集。首先,通过线描增强模块对原始唐卡图像进行边缘增强。然后使用特征提取网络提取特征图。然后,使用半RPN网络来获得感兴趣区域(ROI)。最后,Mask R-CNN Head完成分割和类别预测。实验结果表明,该模型的性能比Mask R-CNN和DeepLab V3等最先进的模型高出10%至19%。
Thangka is a religious scroll painting. As a window to Tibetan traditional culture and religious customs, the segmentation of important semantic objects in the images can help the public understand the image content and realize high-level semantic cognition of the visual content. This paper proposes a semantic segmentation network for the central figures’ headdresses in the portrait-type Thangka images based on the rich structure and standard composition of Thangka images. Meanwhile, it has also constructed the first pixel-level semantic annotation data set of the central figures’ headdresses in Thangka images. Firstly, an original Thangka image witnesses edge augmentation through the line drawing augmentation module. Then the Feature Extraction Network is used to extract the feature map. After that, it uses the Half-RPN network to get the region of interest (ROI). Finally, Mask R-CNN Head completes segmentation and class prediction. The experimental results show that the performance of the proposed model is 10% to 19% better than that of the state-of-the-art models such as Mask R-CNN and DeepLab V3.
