  • Video Enhancement with Task-Oriented Flow
    International Journal of Computer Vision, 2019
    Co-Authors: Baian Chen, Jiajun Wu, William T. Freeman
    Abstract:

    Many video enhancement algorithms rely on optical flow to register frames in a video sequence. Precise flow estimation is however intractable; and optical flow itself is often a sub-optimal representation for particular video processing tasks. In this paper, we propose task-oriented flow (TOFlow), a motion representation learned in a self-supervised, task-specific manner. We design a neural network with a trainable motion estimation component and a video processing component, and train them jointly to learn the task-oriented flow. For evaluation, we build Vimeo-90K, a large-scale, high-quality video dataset for low-level video processing. TOFlow outperforms traditional optical flow on standard benchmarks as well as our Vimeo-90K dataset in three video processing tasks: frame interpolation, video denoising/deblocking, and video super-resolution.

  • GLOBECOM - Power-Efficient Video Uploading for Crowdsourced Multi-View Video Streaming
    2018 IEEE Global Communications Conference (GLOBECOM), 2018
    Co-Authors: Than Than Nu, Takuya Fujihashi, Takashi Watanabe
    Abstract:

    Exploiting the inter-camera correlation among the crowdsourced mobile video contributors is desirable as it can improve the coding efficiency and/or video quality. This can be achieved by using a digital video encoder such as H.264/Multi-view Video Coding (MVC). However, highly-complex nature of digitalbased video encoding requires a large amount of power, which is a limited resource of the consumer-grade mobile devices. In addition to video encoding, transmission power is also consumed for video uploading based on the amount of uploading video traffic to satisfy video quality requirement. In this paper, we propose a powerefficient video uploading scheme for crowdsourced multi- view video streaming considering power-saving in both video encoding and video transmission. To this end, we design a cluster-based redirect transmission scheme. In this scheme, video frames of multiple contributors are only encoded by four-dimensional discrete cosine transform (4D-DCT) and modulated by near-analog modulation at a cluster head. By removing digital-based coding and modulation, our scheme achieves the same video quality with the existing scheme under low power requirements. Evaluation results show that the proposed scheme outperforms the digital-based video uploading schemes in terms of video quality and the amount of video traffic to achieve a targeted video quality.

  • Patriarchal unions = weaker unions? Industrial relations in the Asian garment industry
    Third World Quarterly, 2017
    Co-Authors: Alice Evans
    Abstract:

    AbstractThis paper explores how gender ideologies shape industrial relations in the Asian garment industry. Drawing on ethnographic research, it illustrates how widespread norm perceptions of acquiescent women and assertive men reinforce patriarchal, authoritarian unions. Even if privately critical, women may be reluctant to protest if they anticipate social disapproval. Such beliefs reinforce patriarchal unions, curbing women workers’ collective analysis, engagement, and activism. This weakens the collective power of labour to push for better working conditions. Tackling norm perceptions and building more inclusive unions may help strengthen the labour movement.Video abstractRead the transcriptWatch the video on Vimeo
