Translating Adult's Focus of Attention to Elderly's
2021
Predicting which part of a scene elderly people would pay attention to could be useful in assisting their daily activities, such as driving, walking, and searching. Many computational models for predicting focus of attention (FoA) have been developed. However, most of them focus on mimicking adult FoA and do not work well for predicting elderly's, due to age-related changes in human vision. Is it possible to leverage the prediction results made by an FoA model of general adults to accurately predict elderly's FoA, rather than training a new network from scratch? In this paper, we consider a novel problem of translating adult's FoA to elderly's and propose an approach based on deep image-to-image translation. Our model is trained by minimizing both Kullback-Leibler divergence and adversarial loss to approximate the joint probability distribution of adult and elderly FoA. Experiments on two datasets demonstrate that our model gives remarkable prediction accuracy.
