摘要:

人类感知世界使用多模态感官输入,如视觉,听觉和触觉。在这项工作中,我们研究视觉和触觉之间的跨模态连接。这种跨领域建模任务的主要挑战在于两者之间的显著尺度差异:虽然我们的眼睛一次感知整个视觉场景,但人类在任何给定时刻只能感受到物体的一小部分。为了连接视觉和触觉,我们引入了新的任务,即从视觉输入中合成看似合理的触觉信号,以及想象我们如何与给定触觉数据作为输入的物体进行交互。为了实现我们的目标,我们首先为机器人配备视觉和触觉传感器,并收集相应的视觉和触觉图像序列的大规模数据集。为了缩小规模差距,我们提出了一个新的条件对抗模型,该模型结合了触摸的规模和位置信息。人类感知研究表明,我们的模型可以从触觉数据产生逼真的视觉图像,反之亦然。最后,我们提出了关于不同系统设计的定性和定量实验结果,以及可视化我们模型的学习表示。

英文摘要:

Humans perceive the world using multi-modal sensory inputs such as vision, audition, and touch. In this work, we investigate the cross-modal connection between vision and touch. The main challenge in this cross-domain modeling task lies in the significant scale discrepancy between the two: while our eyes perceive an entire visual scene at once, humans can only feel a small region of an object at any given moment. To connect vision and touch, we introduce new tasks of synthesizing plausible tactile signals from visual inputs as well as imagining how we interact with objects given tactile data as input. To accomplish our goals, we first equip robots with both visual and tactile sensors and collect a large-scale dataset of corresponding vision and tactile image sequences. To close the scale gap, we present a new conditional adversarial model that incorporates the scale and location information of the touch. Human perceptual studies demonstrate that our model can produce realistic visual images from tactile data and vice versa. Finally, we present both qualitative and quantitative experimental results regarding different system designs, as well as visualizing the learned representations of our model.
