Appearance-based gaze estimation has been very successful with the use of deep learning. Many following works improved domain generalization for gaze estimation. However, even though there has been much progress in domain generalization for gaze estimation, most of the recent work have been focused on cross-dataset performance -- accounting for different distributions in illuminations, head pose, and lighting. Although improving gaze estimation in different distributions of RGB images is important, near-infrared image based gaze estimation is also critical for gaze estimation in dark settings. Also there are inherent limitations relying solely on supervised learning for regression tasks. This paper contributes to solving these problems and proposes GazeCWL, a novel framework for gaze estimation with near-infrared images using contrastive learning. This leverages adversarial attack techniques for data augmentation and a novel contrastive loss function specifically for regression tasks that effectively clusters the features of different samples in the latent space. Our model outperforms previous domain generalization models in infrared image based gaze estimation and outperforms the baseline by 45.6\% while improving the state-of-the-art by 8.6\%, we demonstrate the efficacy of our method.

Towards Fine-grained Visual Representations by Combining Contrastive Learning with Image Reconstruction and Attention-weighted Pooling

本文介绍了对比重建,ConRec -一种自监督学习算法,通过联合优化对比和自重建损失来获得图像表示。我们展示了最先进的对比学习方法(例如Simplified)在其表示中捕获细粒度视觉特征方面存在缺陷。ConRec通过添加(1)自我重建任务和(2)对比学习任务中的注意力机制扩展了Simplified框架。这是通过应用具有两个头的简单编码器-解码器架构来实现的。我们表明,这两个扩展有助于改善图像的矢量表示与细粒度的视觉特征。结合这些概念,ConRec在细粒度分类数据集上的性能优于Simplified和Simplified with Attention-Pooling。

短语基础,将图像区域与字幕词相关联的问题,是视觉语言任务的重要组成部分。我们表明,短语接地可以通过优化字区域的注意,以最大限度地提高图像和字幕词之间的互信息的下限。给定成对的图像和字幕,我们最大限度地提高了注意力加权区域和相应字幕中的单词的兼容性,相比于非对应的图像和字幕对。其核心思想是通过语言模型指导的词替换来构造有效的负面字幕。与来自训练数据的随机采样负数相比,使用我们的负数进行训练会在准确性方面产生$\sim10\%$绝对增益。我们在COCO-Captions上训练的弱监督短语接地模型显示了$5.7\%$的健康增益,以在Flickr 30 K Entities基准上实现$76.7\%$准确性。
