Abstract:Visual kinship recognition aims to identify blood relatives from facial images. Its practical application-- like in law-enforcement, video surveillance, automatic family album management, and more-- has motivated many researchers to put forth effort on the topic as of recent. In this paper, we focus on a new view of visual kinship technology: kin-based face generation. Specifically, we propose a two-stage kin-face generation model to predict the appearance of a child given a pair of parents. The first stage includes a deep generative adversarial autoencoder conditioned on ages and genders to map between facial appearance and high-level features. The second stage is our proposed DNA-Net, which serves as a transformation between the deep and genetic features based on a random selection process to fuse genes of a parent pair to form the genes of a child. We demonstrate the effectiveness of the proposed method quantitatively and qualitatively: quantitatively, pre-trained models and human subjects perform kinship verification on the generated images of children; qualitatively, we show photo-realistic face images of children that closely resemble the given pair of parents. In the end, experiments validate that the proposed model synthesizes convincing kin-faces using both subjective and objective standards.
Abstract:Multi-modal human motion analysis is a critical and attractive research topic. Most existing multi-modal action datasets only provide visual modalities such as RGB, depth, or low quality skeleton data. In this paper, we introduce a new, large-scale dataset named EV-Action dataset. It consists RGB, depth, electromyography (EMG), and two skeleton modalities. Compared with others, our dataset has two major improvements: (1) we deploy a motion capturing system to obtain high quality skeleton modality, which provides more comprehensive motion information including skeleton, trajectory, and acceleration with higher accuracy, sample frequency, and more skeleton markers. (2) we include an EMG modality. While EMG is used as an effective indicator for biomechanics area, it has yet to be well explored in multimedia, computer vision, and machine learning areas. To the best of our knowledge, this is the first action dataset with EMG modality. In this paper, we introduce the details of EV-Action dataset. A simple yet effective framework for EMG-based action recognition is proposed. Moreover, we provide state-of-the-art baselines for each modality. The approaches achieve considerable improvements when EMG is involved, and it demonstrates the effectiveness of EMG modality in human action analysis tasks. We hope this dataset could make significant contributions to signal processing, multimedia, computer vision, machine learning, biomechanics, and other interdisciplinary fields.
