摘要:

漫画的人脸识别与视觉图像的识别相比,其表现效果相差甚远。挑战在于通过夸大面部特征来加强角色的极端非刚性扭曲。在本文中,我们提出了基于深度CNN的动态多任务学习,用于跨模态漫画视觉人脸识别。与传统的固定任务权值的多任务学习不同,动态多任务学习根据任务的重要性动态更新任务权值,使网络的训练集中在硬任务上,而不是停留在简单任务的过度训练上。实验结果证明了动态多任务学习在漫画-视觉人脸识别中的有效性。在数据集CaVI和WebCaricature上进行的性能评估显示了优于最先进方法的优越性。实现代码可以在这里找到。

英文摘要:

Rather than the visual images, the face recognition of the caricatures is far from the performance of the visual images. The challenge is the extreme non-rigid distortions of the caricatures introduced by exaggerating the facial features to strengthen the characters. In this paper, we propose dynamic multi-task learning based on deep CNNs for cross-modal caricature-visual face recognition. Instead of the conventional multi-task learning with fixed weights of the tasks, the proposed dynamic multi-task learning dynamically updates the weights of tasks according to the importance of the tasks, which enables the training of the networks focus on the hard task instead of being stuck in the overtraining of the easy task. The experimental results demonstrate the effectiveness of the dynamic multi-task learning for caricature-visual face recognition. The performance evaluated on the datasets CaVI and WebCaricature show the superiority over the state-of-art methods. The implementation code is available here.
